What does a cybersecurity analyst do?
If you are wondering, "What does a cybersecurity analyst do?", here are the core responsibilities to consider:
Investigating security breaches
Cybersecurity analysts often investigate and report the vulnerabilities in an IT infrastructure. They assess a company's software programs to identify potential breaches and security issues. If they find any malicious software, they may strengthen the security. The role typically requires that they conduct forensics at a digital crime scene. Digital forensics is the process of interpreting, analyzing, documenting, and presenting electronic data to use as evidence.
Cybersecurity analysts often conduct this forensic procedure to check encrypted data, recover deleted files, determine passwords, and find the source of a security breach. These professionals also investigate security alerts to determine their risk level and how to mitigate them.
Performing security assessments
Cybersecurity analysts typically use information security standards, data encryption programs, and firewalls to assess risks. These professionals may evaluate a business's compliance with industry standards and regulatory requirements. Doing this can help them find areas to improve in the current security system. They perform external and internal audits on an organization's computer networks to determine if it can handle cyberattacks. After these professionals conduct an assessment, they compile a detailed report to document a company's security issues and the methods they implemented in response.
Installing operating security software
Security threats may occur across operating systems on computers and mobile phones. Cybersecurity analysts usually manage, install, and operate security software for companies. For example, they can install system software to prevent malware from entering a network by strengthening its protection and improving security for mobile devices. The role often requires using comprehensive software to protect a company's website and guard network traffic.
It's essential that cybersecurity analysts ensure few individuals have access to an organization's sensitive data to prevent theft. To do this, they may implement identity and access management (IAM). This framework helps ensure that only approved individuals have access to a company's network. It can also protect the organization from ransomware incidents that employees may inadvertently cause. Ransomware is malicious software that denies a company access to the files on its computer.
Developing security and recovery plans
Cybersecurity analysts develop and promote best practices for information technology. They update a company's disaster recovery plan (DRP) to avoid future breaches. This plan is a formal document that contains instructions and strategies on how a company may respond to cyberattacks. These professionals also ensure that an organization has backups in the situation of a data breach. They can discuss system weaknesses and suggest improvements to management and IT staff. Cybersecurity analysts educate other employees on cybersecurity to mitigate risk.
Researching security trends
As cybersecurity analysts work with technology resources, it's vital they remain current with IT trends. This can help them understand new threats a company may face to develop preventive measures. These professionals research advanced systems and techniques among hackers. They're also conversant with new terminologies and words in the technology sector.
Ethical hacking is the practice of gaining access to a network to expose security risks. Cybersecurity analysts usually perform it with the approval of an organization. These professionals may conduct ethical hacking to check a network's vulnerability through simulating attacks and penetration testing. These security testing methods often mimic a malicious software's likely attack path to identify vulnerabilities in a network environment. While performing ethical hacking, they may use software applications and manual coding knowledge to hack and exploit a company's system and determine ways to fix it.
Work environment of a cybersecurity analyst
Cybersecurity analysts typically work in corporate offices and laboratories, while others may work remotely. They often work for an average of seven to eight hours daily. As cyberattacks can occur anytime, these professionals may work on weekends and outside business hours to ensure data security. Common employers may include tech companies, government agencies, e-commerce websites, private firms, IT firms, and financial institutions. These professionals can work with other analysts or collaborate with computer security specialists to protect a company's computer system.
What are the relevant skills of a cybersecurity analyst?
The following are the relevant skills that can help cybersecurity analysts perform their role successfully:
Data is a valuable resource for many companies. Professionals with this skill can protect data through encryption, internet protocols, and access management.
