As a cyber security analyst, you are the vigilant guardian of an organization’s digital assets. To protect them, you must use security analytics solutions that monitor both internal and third-party risks.
This requires a strong foundation in technical knowledge and attention to detail. It also demands the ability to communicate clearly with both technical and non-technical teams.
1. Detecting Malware
Malware is software that infiltrates or damages a computer system without lawful authorization. It can take many forms, including ransomware, spyware, Trojans, scareware, bots, rootkits, worms, and viruses. Cybersecurity analysts study malware to get useful information about the threat, so they can better stop it and prevent future attacks.
Identifying and understanding what the malware does allows cybersecurity teams to detect it and protect against it in real-time. They can do this through a combination of static analysis (examining the file’s metadata and properties without running it) and dynamic analysis (running a malware sample in a safe environment).
Insights from this malware analysis help develop detection tools, like signatures, heuristic detection methods, and behavioral analysis systems. It also helps determine what kind of vulnerabilities hackers may exploit, so IT departments can prioritize patching and hardening efforts.
Additionally, knowing the nature of malware enables security teams to find and blacklist websites that propagate it, as well as to better understand what kinds of threats are attacking them. All of this helps to speed up incident response times and makes it easier for security teams to remediate incidents. It also helps them meet regulatory compliance requirements, such as ensuring that data privacy regulations are being followed.
2. Identifying Vulnerabilities
Cybersecurity analysis, or vulnerability assessment, is a method of discovering and classifying security weaknesses in information systems, networks, applications, and digital assets. It’s also a valuable tool for identifying and understanding the potential threats those vulnerabilities represent.
A vulnerability is a flaw, weakness, or lack of protection that attackers can exploit to gain entry into your system and cause harm. Vulnerabilities can exist in a variety of ways, from human mistakes (like employees falling for phishing or smishing attacks) to technical issues (like outdated software, misconfigurations, and unprotected data).
By conducting vulnerability assessments, cybersecurity analysts can discover these risks before bad actors are able to take advantage of them. This allows for better risk management and the identification of controls that can be put in place to prevent or mitigate these risks before they become a threat.
Vulnerability assessments are often conducted using automated tools and penetration testing, but can also be performed manually or with the help of other methodologies such as a Failure Mode and Effects Analysis (FMEA).
FMEA is a methodology for assessing the likelihood of a threat occurring and its impact on operations and is often used in conjunction with vulnerability assessment. This helps prioritize the severity of vulnerabilities and the urgency of their remediation and can be a useful way to communicate these risks to non-technical stakeholders.
3. Remediating Vulnerabilities
Cybersecurity analysis requires a rare mix of technical prowess and soft skills like critical thinking and attention to detail. It’s a high-stakes vocation, and successful cybersecurity analysts can make or break a business.
One of the most important aspects of a good cybersecurity strategy is knowing how to remediate vulnerabilities. This is the process of fixing and neutralizing potential threats that could cause data breaches, DDoS attacks, malware, or phishing. It involves an organized process involving multiple departments, including development, operations, compliance, and risk management to determine the best way to resolve each vulnerability.
The first step is cataloging all of the IT assets in your business and identifying which are vulnerable to attacks. This can be done by using a tool that provides increased visibility into your IT environment, such as NinjaOne’s IT asset management software. Once you have a complete inventory of your IT assets, you can begin to rank them based on their severity and prioritize remediation efforts accordingly.
When determining the priority of each vulnerability, you must consider its risk level, exploitability, and impact on affected systems. This allows you to focus your resources on addressing the most critical vulnerabilities first, while also minimizing the risk of attack and protecting the rest of your digital ecosystem. With this, you can prevent future cyberattacks and reduce your overall security risk.
4. Defending Against Malware
Cybersecurity analysis involves examining malware to understand its capabilities and impact. The information gleaned from this can help cybersecurity teams build effective threat detection and response solutions.
This is done through static or dynamic malware analysis. Static malware analysis examines the threats without executing them, such as by using tools like disassemblers and network analyzers. Dynamic malware analysis, on the other hand, allows analysts to run suspicious code in a controlled environment (called a sandbox) to see how it behaves without risking infection of the main system.
Both approaches are necessary to understand how to defend against malware. By analyzing malware, cybersecurity professionals can gain insight into how attackers bypass security controls. In addition, they can identify indicators of compromise (IoCs) and create detection rules to prevent future incidents.
Defending against malware requires visibility into the entire IT ecosystem, including third-party networks. However, the complexity of these IT ecosystems makes this challenging. Fortunately, malware analysis helps to overcome this challenge by identifying and understanding vulnerabilities at all levels of the system’s architecture.
Malware can be used for a variety of purposes, such as data espionage, stealing identity information, and stealing resources. Moreover, cyberattackers often design their malware to evade security measures such as firewalls, intrusion detection systems, and encryption software. As a result, cybersecurity analysts must use a variety of techniques to detect and mitigate malware.
