How to Become an Information Security Analyst



Information security analysts monitor private data. To protect information and network infrastructure from attacks, infosec professionals create firewalls and update software systems. 

Most infosec professionals work in IT departments providing security and consultation services for firms, businesses, and financial companies. They analyze security protocols and look for weaknesses in a company’s security system, stopping attacks before they happen. 

If you wish to pursue employment in this sector, you’ve come to the right place. Use this guide to decide whether a career in information security is for you. 

What Is Information Security? 

Information security is the practice of protecting data from unauthorized access or theft. The three major principles of information security are secrecy, integrity, and availability, also known as the CIA triad. The techniques of infosec specialists are designed and implemented to guard against the misuse, disclosure, or destruction of personal data.

What Is Information Security Used For?

For many organizations, information is a prized asset that must be protected at all costs. Information security is mainly used for four things.

  • Encipherment. This refers to making data unreadable to unauthorized parties. It is achieved mainly by employing the arts of cryptography and steganography.

  • Data Integrity. Infosec analysts must ensure that important data has not been tampered with, or that companies can check whether their data is intact. 

  • Access Control. By regulating who can view the data, information security analysts can minimize the risk of unauthorized access.

  • Notarization. This is a security mechanism that involves the use of trusted third parties in the transfer of information. Notaries keep a record of all the requests made by the sender to the receiver for any later denial.

What Is an Information Security Analyst?

Information security analysts are responsible for ensuring that a company’s digital assets are protected from unknown threats. 

They do this in many ways. They analyze security breaches to find the root cause of a problem and perform security audits to diagnose weak points in a system. By writing reports for business managers on the efficacy of existing security policies, they can help a company take steps towards a safer and more secure network. 

Information Security Analyst Skills 

To protect a network from cyber threats, you must have a few skills at your disposal. The most important are the following three.

Vulnerability Management Skills

Susceptibility management is the process of identifying, reporting on, and treating weaknesses in the system and the software installed in the system. 

You will be better prepared to help an organization prioritize possible threats if you know something about ethical hacking, intrusive prevention, and computer forensics. 

Big Data Infosec Skills 

Big data information security means guarding both the data and analytics from attack, theft, or any malicious activity that may cause harm to the data. 

One of the most common tools is encryption, which renders the encrypted data useless to hackers. Building a strong firewall is another helpful tool for securing big data. Any information security analyst should know how and when to use these tools.

Cloud Security Skills

Cloud security focuses on creating and hosting secure applications in a cloud environment. Given recent advances in cloud technology, infosec analysts must be equipped to handle cloud-based systems, their data, and infrastructure. 

Roles and Responsibilities of an Information Security Analyst 

A security analyst secures data from unauthorized access by creating a system that can prevent attacks. An information security analyst has several roles. 

It includes operating infosec software and controls, communicating through all levels of the organization and creating, modifying, and updating the intrusion detection system (IDS). 

Below are a few more duties that an analyst must perform.

  • Monitoring networks. A system analyst monitors an organization’s networks for security breaches and thefts and then investigates violations when any occur. 

  • Prescribing security software. They install firewalls and data encryption software to protect all of an organization’s sensitive information and data.

  • Conducting penetration testing. Penetration testing is used to identify vulnerabilities in a system before they can be exploited. The analyst simulates attacks and then looks for such loopholes.

  • Implementing incident response plans. Perhaps an organization needs to take preventive measures such as transferring data to an offsite location. Or it needs to find new data security technologies that will more effectively protect itself.

Information Security Analyst Job Opportunities 

A certified information systems security professional is one of the most valuable job titles you can get. If you have the requisite theoretical and practical knowledge, you can get prime placement working for a computer company, a consulting firm, or a financial business. 

According to the US Bureau of Labor Statistics, the demand for information security analysts is projected to rise by 31 percent over the next 10 years. It is much faster than the average for all occupations. 

Information Security Analyst Salary 

According to PayScale, the average salary for an information security analyst in the United States is $72,676, with a range of $60,000 to $90,000. Bonuses are often awarded to infosec professionals for exceptional job performance.
