What are Insider Threats? Types, Prevention & RisksThreat Intelligence

What are Insider Threats? Types, Prevention & Risks

Insider threats refer to risks posed by individuals within an organization. This guide explores the types of insider threats, their potential impacts, and strategies for prevention. Learn about the importance of employee awareness and monitoring in mitigating insider risks. Understanding insider threats is crucial for organizations to protect sensitive information and maintain security. What are Insider Threats? Insider threats refer to security breaches that originate from people within an organization. These individuals have authorized access to sensitive information, such as customer data, financial information, and intellectual property. Insider threats can result in significant financial losses, reputational damage, and legal liabilities for organizations. Types of Insider Threats Insider threats can take many forms, and they are not always malicious. In some cases, employees may inadvertently cause a security breach by clicking on a phishing email or using a weak password. In other cases, employees may intentionally cause harm for financial gain, revenge, or to obtain sensitive information. There are three main categories of insider threats: Careless or Unintentional Threats – These types of insider threats occur when an employee or contractor unintentionally causes a security breach. This can happen through a lack of awareness or training or simply by making a mistake. Malicious Insider Threats – Malicious insider threats occur when an employee or contractor intentionally causes harm to the organization. This can be for financial gain, revenge, or to obtain sensitive information. Compromised Insider Threats – A compromised insider threat occurs when an attacker gains access to an employee’s or contractor’s account or system and uses it to carry out an attack. This can happen through phishing attacks, social engineering, or other means. Real-World Examples of Insider Threats Several high-profile insider threat cases have made headlines in recent years. For example, the data breach at Equifax in 2017 was caused by an insider who exploited a vulnerability in the company’s web application to steal the sensitive data of 143 million customers. Another example is the case of Edward Snowden, who leaked classified information from the National Security Agency (NSA) in 2013. Preventing Insider Threats Preventing insider threats requires a multi-layered approach that involves people, processes, and technology. Here are some practical steps organizations can take to protect themselves from insider threats: Educate employees – Provide regular security awareness training to employees, contractors, and third-party vendors. Implement access controls – Limit access to sensitive data based on the principle of least privilege. Use two-factor authentication, role-based access control, and other access control mechanisms. Monitor and audit user activity – Implement logging and monitoring solutions to detect anomalous behavior and identify potential insider threats. Enforce security policies – Have clear security policies and enforce them rigorously. Why Are Insider Threats Significant? Insider threats can be particularly harmful to organizations because insiders already have access to sensitive data and systems. This means they do not need to bypass any security controls to cause harm, making them a more challenging threat to detect and prevent. Moreover, insiders can cause significant damage to an organization’s reputation, financial stability, and legal standing. For example, insiders who steal intellectual property or sensitive customer information can damage an organization’s reputation and credibility. Insiders who disrupt network operations can cause significant financial losses and impact an organization’s ability to provide customer services. In addition, insider threats are becoming more prevalent and sophisticated, making it challenging for organizations to keep up. According to Gurucul’s 2023 Insider Threat report, in 2022, there was a significant increase in insider attacks as 74% of organizations report that attacks have become more frequent (a 6% increase over last year), with 60% experiencing at least one attack and 25% experiencing more than six attacks. How To Address the Risk of Insider Threats Develop a comprehensive insider threat program – To address insider threats; organizations should develop a comprehensive program that includes policies, procedures, and technologies. This program should cover all aspects of insider risk, including employee monitoring, access control, and incident response. Conduct regular security awareness training – Regular security awareness training can help employees understand the risks of insider threats and how to avoid them. Employees should be trained on best practices for password management, social engineering attacks, and how to report suspicious activities. Monitor employee activities – Monitoring employee activities is critical to detecting and preventing insider threats. This can include monitoring employee emails, file transfers, and network activity. However, organizations must balance the need for monitoring with employees’ privacy rights and legal requirements. Implement access controls – Access controls can help limit the exposure of sensitive data and systems to insiders. Organizations should implement role-based access controls, ensuring employees have access only to the data and systems necessary to perform their job duties. Access controls should also be regularly reviewed and updated to remain effective. Use XDR and anti-malware software – XDR (Extended Detection and Response) is a next-generation security technology that provides real-time threat detection and response across multiple vectors, including endpoints, networks, and cloud environments. Anti-malware software can help detect and prevent malicious software from being installed on employees’ devices. With XDR, enterprises can identify abnormal access and user behavior, enabling the detection of such attemp.ts Conduct background checks – Organizations should conduct thorough background checks on employees, contractors, and third-party partners before granting them access to sensitive data and systems. Background checks can help identify potential insider threats, such as individuals with a history of theft or fraud. Implement incident response procedures – Organizations should have incident response procedures to respond quickly and effectively to insider threats. These procedures should include steps for reporting and investigating incidents, identifying the root cause of the incident, and implementing corrective actions to prevent similar incidents from occurring in the future. Conclusion Insider threats are a significant and growing risk for organizations of all sizes and industries. Insiders accessing an organization’s sensitive data and systems can cause significant harm, intentionally or unintentionally. Given the potential impact of insider threats, organizations must take steps to mitigate this risk. A comprehensive insider threat program that includes policies, procedures, and technologies to detect and prevent insider threats is critical. Organizations should also conduct regular security awareness training, monitor employee activities, implement access controls, use encryption and DLP technologies, conduct background checks, and implement incident response procedures. By taking these steps, organizations can reduce the risk of insider threats and protect their sensitive data, systems, and reputation. Remember, the best defense against insider threats is a proactive and comprehensive approach that involves all levels of the organization, from the executive team to the front-line employees.

What is a Threat Actor? Types & ExamplesThreat Intelligence

What is a Threat Actor? Types & Examples

Threat actors are individuals or groups that carry out cyber attacks. This guide explores the different types of threat actors, their motivations, and tactics. Learn about the importance of understanding threat actors in developing effective cybersecurity strategies. Understanding threat actors is crucial for organizations to anticipate and mitigate risks. This article will review what threat actors are, threat actor targets, types of threat actors, and how to prevent their attacks. What is a Threat Actor? A cyber threat actor is any individual or group that poses a threat to cybersecurity. Threat actors are the perpetrators behind cyberattacks, and are often categorized by a variety of factors, including motive, type of attack, and targeted sector. Today, the cyber threat environment is arguably more dynamic than ever before and threat actors are becoming more sophisticated. Understanding threat actors and their motives can help organizations better protect themselves from the damage these actors cause as they exploit vulnerabilities, compromise user identities with elevated privileges, evade security controls, damage or delete data, or manipulate sensitive information. Threat Actor Targets Threat actors primarily target large organizations for monetary gain, data, and sensitive intelligence, or to cause service disruption and reputational harm. However, small and medium-sized businesses (SMBs) have also become frequent targets for threat actors because their relative lack of resources can mean that their security systems are weaker than those of large enterprises. In today’s threat landscape, most organizations are likely to be targeted by a threat actor, regardless of their size or industry. In fact, businesses faced 50% more cyberattack attempts per week in 2021 compared to 2020. Today, threat actors can and will find a path straight to the crown jewels if the path is unprotected. Threat Actor Types and Attributes “Threat actor” is a broad term that encompasses a wide variety of individuals and groups categorized based on their skill set, resources, or motivation for attack. Here are some of the most common types of threat actors and the motivations typically behind their actions: 1. Cybercriminals Cybercriminals are individuals or groups who use digital technology to conduct illegal activity. They’re often motivated by financial gain. This type of threat actor typically employs social engineering tactics such as phishing emails to lure victims into clicking on a malicious link or downloading malicious software (malware). Other examples of cybercrime include stealing data, tricking victims into transferring money, stealing login credentials, and making ransom demands. 2. Nation-States Nation-states may fund threat actor groups to perform a variety of malicious activities on the networks of other governing entities including espionage or cyberwarfare. Since nation-state funded threat actors tend to be highly resourced, their behavior is often persistent and more difficult to detect. Targeting their opponents’ networks in stealth, nation-state-funded threat actors typically seek to exfiltrate or corrupt sensitive data and assets, disrupt critical infrastructure, or gather confidential intelligence. 3. Terrorist Groups As with physical acts of terrorism, the goal of cyber terrorists is typically to cause harm and destruction that furthers their cause. This type of threat actor targets businesses, state machinery, and critical infrastructures or services that will cause the most damage or disruption. 4. Thrill-Seekers Thrill-seekers are threat actors who attack computer systems or networks for personal enjoyment. Whether they want to see how much data and sensitive information they can steal, or they are interested in how specific networks and computer systems operate, thrill-seekers may not necessarily intend to do much harm to their targets. However, they can interfere with computer systems and networks or exploit vulnerabilities for more sophisticated cyberattacks in the future. 5. Insider Threats Insider threats are on the rise. These threats can be categorized into the following types: Malicious Insiders: Malicious insiders are individuals who have access to the corporate environment and decide to turn against their employers by helping threat actors; usually for monetary gain. Incautious Insiders: Incautious insiders are employees who may not have malicious intent but end up causing a data breach due to their carelessness. They might click on a phishing email, install unapproved software, or lose their corporate devices. 6. Hackers Although the term ‘threat actor’ is often used interchangeably with ‘hackers’, hackers and threat actors are not one and the same. A hacker is someone who uses their computer skills to overcome a challenge or problem, for better or for worse, while threat actors almost always have malicious intent. Hollywood popularized the term to invoke images of nefarious individuals with malicious intentions, such as causing disruption or breaking the law. However, there are many types of hackers with different capabilities. Here are some examples of different types of hackers and what they can do: Black Hat Hackers Black hat hackers work against organizations or government agencies in an attempt to break into computer networks or systems with malicious intent. Black hat hackers often work alone or with organized crime groups and employ a number of techniques to hack their targets, including social engineering, hacking passwords, infecting devices with malware, logging keystrokes, or creating botnets to execute a Distributed-Denial-of-Services (DDoS) attack. White Hat Hackers White hat hackers, also called ethical hackers, work with organizations or government agencies to identify vulnerabilities and protect cyber systems from malicious hackers. Unlike other types of hackers, white hat hackers always have permission from the organization or agency they work with to hack into computer networks or systems. Grey Hat Hackers Grey hat hackers fall somewhere in between white hat hackers and black hat hackers. Grey hat hackers hack into computer networks or systems in order to draw the target’s attention to vulnerabilities or potential attack paths and then charge a fee to fix the issues they’ve discovered. Most often, this type of hacker exploits security issues without malicious intent, but it is done without permission and often through illegal tactics. Green Hat Hackers Green hat hackers are beginners and often seek out information from more experienced members of the hacking community. Although green hat hackers may not always have the necessary skills or knowledge to launch a coordinated attack, they can still cause serious damage if they don’t have a clear understanding of what they’ve done or how to fix it. Blue Hat Hackers Blue hat hackers are most similar to white hat hackers: they’re security professionals working at consulting firms that are hired specifically to test a system prior to its launch. Sometimes, blue hat hackers also target individuals or companies in retaliation for some wrongdoing without putting much thought into the consequences of their actions. Red Hat Hackers Red hat hackers are often seen as the “dark horses” of the hacking world, working alone or in private groups to disarm black hat hackers. Unlike white hat hackers who turn black hat hackers into the authorities, red hat hackers often focus on destroying resources and doing harm. Script Kiddies Unlike other types of hackers, script kiddies are often motivated by boredom and don’t write their own computer scripts or code. Instead, they insert existing scripts or codes into viruses or applications to hack computer systems belonging to others. In the hacking world, script kiddies are notorious for being relatively unskilled and immature compared to other types of hackers. Hacktivists Hacktivists are often considered black hat hackers, but their motivations for hacking are political. Whether they’re concerned with preserving free speech or exposing instances of human rights violations, hacktivists target individuals, organizations, or government agencies. Most of the time, hacktivists believe they’re trying to enact a positive change in the world. For example, the hacking group Anonymous is well-known for its numerous cyberattacks against several governments and have been called “freedom fighters” by their supporters. Of the different types of hackers, the term “threat actor” most directly applies to black hat hackers, blue hat hackers, script kiddies, and hacktivists. Whether it’s cybercriminals or insiders, Singularity’s threat intelligence helps track and defend against all types of threat actors. Related Cybersecurity Concepts to Know In addition to understanding the essential components of threat actors and their attributes, it’s helpful to review these cybersecurity concepts: Malware Malware is a type of malicious software that is designed to damage or disable computers. Malware can be used to steal data, take control of systems, or launch attacks on other computers. There are many different types of malware, including viruses, worms, Trojans, and ransomware. Malware can be spread through email attachments, infected websites, or compromised software. Phishing Phishing is a type of cyberattack that uses emails or websites that appear to be from legitimate sources in order to trick users into disclosing sensitive information or clicking on malicious links. Phishing attacks can be very difficult to detect because they often use spoofed email addresses and websites that look similar to legitimate ones. Attackers will also target specific individuals or organizations in order to increase their chances of success. Denial-of-Service Attack A Denial-of-Service attack (DoS attack) is a type of cyberattack that attempts to make a system or network unavailable to users. DoS attacks target websites or online services and can be used to take down entire systems. DoS attacks are usually carried out by flooding the target with traffic or requests until it can no longer handle the load and becomes unavailable. They can also be used to disable systems or networks by corrupting data, taking advantage of vulnerabilities, or overloading resources. Ransomware Ransomware is a type of malware that encrypts files or locks systems, making them inaccessible to users. It can be spread through email attachments, infected websites, or compromised software. This type of malware blocks access or encrypts assets, often forcing the user to pay a ransom to regain access to their device, files, or system. Thinking of ransomware as simple encryption of randomly stolen data is no longer an accurate representation of the plethora of today’s data extortion strategies. Ransomware actors have recently turned toward data theft instead of time-expensive encryption. Trends indicate that full encryption of victim data is often too arduous and slow for many threat actors, and increases the risk of detection. What’s emerged is a spectrum of threat actors who are moving past traditional, time-consuming encryption and focused on destroying all stolen data. Now, actors are seen prioritizing faster attacks either through data extortion where the data is more or less preserved, or only partial corruption allowing them to move quickly and demand increasingly larger ransom demands. Drive-by Download A drive-by download is a type of cyberattack that involves infecting a system with malware without the user’s knowledge or consent. Drive-by downloads usually happen when a user visits an infected website or clicks on a malicious link. This form of attack can be used to install all types of malware, including viruses, Trojans, and ransomware. Threat Actor Examples Some threat actors may be lone attackers while others may be part of a larger, organized crime ring or cyber threat organization. Reviewing some recent examples of cyberattacks can help organizations better anticipate what type of threat actor might target their networks or systems and prepare for similar incidents in the future. MeteorExpress In July of 2021, a wiper attack – an attack using malware designed to erase the hard drive of the computer it infects – crippled the Iranian national railway system. Once successfully hacked, the displays instructed railway passengers to direct any complaints to the phone number of the Iranian Supreme Leader Khamenei’s office. Dubbed “MeteorExpress,” this campaign demonstrates the ways in which a threat actor can use technical skills to gain access to an information system and exploit it for a political purpose. Today, the threat actor behind this attack is still a mystery. 8220 Gang A crimeware group known as 8220 Gang targets cloud infrastructure services including AWS, Microsoft Azure, Google Cloud, Aliyun and Qcloud, to deploy illicit cryptocurrency miners at their victims’ expense. Although the group has operated for years, by mid 2021, new campaigns using long-running sets of infrastructure brought botnet numbers from roughly 2,000 infected hosts up to today’s figure of around 30,000. Threat actors such as 8220 Gang often spend years slowly evolving their campaigns until they become too massive to dismantle. REvil Ransomware REvil ransomware was successfully delivered to thousands of corporate endpoints through a zero-day attack targeting Kaseya VSA servers commonly used by Managed Security Service Providers (MSSPs) and IT management firms. This attack appears to be one of the largest ransomware incidents to date with attackers offering a universal decryption tool for all its victims at a lump sum of $50 million (originally $70 million). Although initially considered a supply chain attack, this well-orchestrated, mass-scale ransomware campaign reveals how lucrative cyberattacks can be for threat actors, and how important a modern endpoint detection and response (EDR) tool is for organizations. Aoqin Dragon Named and tracked as “Aoqin Dragon” by SentinelLabs researchers, this nation-state funded threat actor group is responsible for a cluster of malicious activity dating back to 2013 targeting government, education, and telecommunications organizations across Southeast Asia and Australia. Although the exact motives are unknown, it is likely that this Chinese-linked advanced persistent threat (APT) group’s main focus is espionage. This example illustrates how threat actors can quietly conduct long-lasting campaigns to stay under the radar while conducting espionage operations and continuing to advance their tradeoff. Moshen Dragon Dubbed “Moshen Dragon,” this Chinese-aligned threat actor has been attributed with hijacking legacy security products including Symantec, TrendMicro, McAfee, BitDefender, and Kaspersky to conduct attacks. In addition to the five different malware triads Moshen Dragon deployed, they also used a variety of other tools including an LSA notification package and a passive backdoor known as GUNTERS. Threat actors are often likely to use multiple tactics, techniques, and tools to breach computer systems and networks. Once threat actors establish a foothold, they will often proceed with lateral movement within the network, place a passive backdoor into the environment, harvest as many credentials as possible, and then focus on data exfiltration. How to Prevent & Stop Threat Actor Cyber Attacks The best advice for defenders is to always act under the assumption that their networks already host threat actors. The best way to prevent threat actors is to have a comprehensive security solution in place. The ideal security solution should include the following capabilities: 1. Endpoint Protection, Detection, and Response (EDR) To protect organizations against threat actors, security teams use comprehensive endpoint security solutions like Singularity™ Endpoint with detection and response capabilities. “Endpoint protection” refers to the technology and processes used to defend network endpoints, such as laptops, servers, and mobile devices, from malware and other threats.  EDR tools are different from other security solutions in that they do not only focus on identifying and quarantining specific malware or officially declared incidents. Instead, EDR tools look for anomalous activities and provide alerts to security teams for further investigation. According to Gartner, EDR solutions: Record and store endpoint-system-level behaviors, use various data analytics techniques to detect suspicious system behavior, provide contextual information, block malicious activity, and provide remediation suggestions to restore affected solutions. 2. Zero Trust Security A zero trust security model is an approach to cybersecurity that doesn’t rely on predefined trust levels. Instead, it treats all users, devices, and networks as untrusted until they are verified through continuous authentication and authorization checks. Zero trust architecture can help prevent threat actors from gaining access to computer systems or networks because it does not provide automatic access to sensitive data. Every single user, including employees and contractors, must go through the verification process each time they want to access something. 3. Multi-Factor Authentication Multi-factor authentication (MFA) adds an extra layer of security by requiring users to provide two or more pieces of evidence, or factors, before they can access sensitive data. For example, a user may be required to enter their password and then confirm their identity with a fingerprint or code sent to their mobile phone. MFA is effective against threat actors because it makes it more difficult for unauthorized users to access sensitive data. Even if they have a valid password, they would also need to have the other factor, such as a physical token or smartphone, to gain access to systems or networks. 4. Defense Against Advanced Persistent Threats (APTs) An advanced persistent threat is a cyberattack where criminals work together to steal data or infiltrate systems that often go undetected over an extended period of time. In most cases, these attacks are performed by nation-states seeking to undermine another government. Whereas other cyberattacks such as malware and phishing schemes work in a matter of days, an APT can take place over months or even years. Some of the most common methods used by APTs include: Spear phishing: Sending targeted emails that appear to be from legitimate sources in order to trick users into clicking on malicious links or opening infected attachments. Social engineering: Tricking users into disclosing sensitive information or compromising their systems by using deception tactics such as fake websites or phone calls. Watering hole attacks: Infecting websites that are commonly visited by a target organization’s employees in order to infect their systems when they visit the website. APTs are more difficult to defend against because they are usually carried out by well-funded and sophisticated organizations. However, with the right preparation and security measures in place, it can be much harder for them to succeed. Effective defense against threat actors requires an integrated solution like Singularity XDR, which provides real-time detection and response.

What are Threats, Techniques & Procedures (TTPs)?

Threats, Techniques, and Procedures (TTPs) describe the behavior of threat actors. This guide explores the significance of TTPs in understanding cyber threats and enhancing security measures. Learn about the importance of threat intelligence in identifying and mitigating risks. Understanding TTPs is crucial for organizations to strengthen their cybersecurity strategies. By dissecting TTPs, organizations can enhance their threat intelligence and respond much more effectively. A Brief Overview of TTPs TTPs make up a multifaceted framework and have evolved in response to the growing sophistication of cyber threats. The need for comprehensive strategies to understand, counteract, and respond to them effectively remains a high priority for cybersecurity practitioners. Origin and Evolution TTPs have their roots in the continuous cat-and-mouse game between cyber adversaries and defenders. As cyber threats evolved from basic viruses and worms to complex, targeted attacks, cybersecurity professionals recognized the need to categorize and understand the tactics employed by threat actors. This led to the development of TTPs as a framework for classifying and analyzing cyber threats systematically. Significance and Contemporary Use Nowadays, TTPs are pivotal in shaping cybersecurity strategies. Threats encompass a wide array of risks, from malware and phishing attacks to advanced persistent threats (APTs). Techniques refer to the specific methods employed by threat actors, including social engineering, zero-day exploits, and encryption. Procedures outline the step-by-step processes adversaries follow, such as reconnaissance, infiltration, and data exfiltration. This comprehensive framework enables cybersecurity professionals to dissect the modus operandi (MO) of threat actors and devise countermeasures. TTPs are employed by a diverse range of actors. Nation-state actors leverage advanced TTPs for cyber espionage and cyber warfare, while cybercriminals use them for financial gain through activities like ransomware attacks. Hacktivists employ TTPs to advance their ideological or political agendas, while insider threats exploit these techniques for internal sabotage. Cybersecurity professionals and organizations use TTP analysis to strengthen security postures, detect emerging threats, and improve incident response capabilities. Understanding How TTPs Works A technical perspective on TTPs delves into the underlying mechanics of these elements to provide insight into how they function. Threats – Threats encompass the various risks and potential attacks that can compromise a system or network. These can range from familiar malware like viruses and Trojans to sophisticated threats like APTs. Technical analysis involves threat intelligence feeds, malware analysis, and monitoring network traffic for known threat signatures. Techniques – Techniques refer to the specific methods or mechanisms employed by adversaries to execute their attacks. These encompass an array of technical actions, including exploit development, social engineering, and evasion tactics. Technical examination involves reverse engineering malware, studying attack vectors, and analyzing vulnerabilities in software or systems. Procedures – Procedures outline the step-by-step processes followed by threat actors to achieve their objectives. This includes reconnaissance, infiltration, privilege escalation, data exfiltration, and cover-up activities. Technical analysis includes monitoring network traffic for signs of these procedures, examining log files for suspicious behavior, and identifying command and control (C2) infrastructure. From a technical standpoint, the process often starts with the identification of a potential threat through various means, including intrusion detection systems (IDS), extended detection and response (XDR) solutions, or threat intelligence feeds. Once a threat is identified, its techniques and procedures are scrutinized. For instance, if a malware threat is detected, reverse engineering is employed to dissect its code, revealing its behavior and potential vulnerabilities it exploits. Threat analysts may also use sandboxing techniques to observe the malware’s actions in a controlled environment. If an attack is ongoing, network traffic analysis is crucial to understand the attacker’s tactics and identify indicators of compromise (IoCs). Exploring the Use Cases of TTPs TTPs play a pivotal role in the contemporary threat landscape, serving as a foundation for understanding and countering cyber threats. This section explores how TTPs are employed in the current threat landscape and essential insights for aspiring security practitioners. APT groups are adept at employing sophisticated TTPs. They use advanced techniques to gain unauthorized access, stay persistent in compromised networks, and exfiltrate valuable data over extended periods. APTs often target governments, critical infrastructure, and large corporations. Malware authors leverage various TTPs to distribute malicious software. This includes techniques like social engineering to trick users into downloading malware, exploiting software vulnerabilities for initial access, and using command and control servers for remote control. Phishing campaigns rely on TTPs to deceive victims into revealing sensitive information. This involves crafting convincing emails or websites, impersonating legitimate entities, and employing persuasive lures. For security teams, TTPs are key to shaping more comprehensive cybersecurity strategies. TTPs can help in the following ways: Threat Intelligence – Continuously gather and analyze threat intelligence to understand emerging TTPs, threat actors, and trends in the threat landscape. Incident Response (IR) – Develop robust incident response plans that incorporate TTP analysis for swift detection, containment, and recovery from security incidents. Security Controls – Implement security controls, such as intrusion detection systems (IDS) and intrusion prevention systems (IPS), to detect and block known TTPs. User Training – Educate users about common TTPs like phishing and social engineering to foster a security-aware workforce. Adaptive Defense – Embrace adaptive defense strategies that focus on detecting deviations from normal network behavior, allowing for early TTP detection. Conclusion TTPs are integral in understanding and defending against cyber threats in the current landscape. By staying informed about evolving TTPs, learning from recent use cases, and implementing effective security practices, security practitioners can contribute to protect their organization’s digital assets and networks.
