On this page, readers can learn about security analyst careers. We take a close look at topics like necessary skills, salary potential, and related occupations.<\/p>\r\n\r\n\n \n \n <\/a>\n\n\r\n Since the internet's earliest beginnings, people have explored ways to hijack it. In 1971, researcher Bob Thomas created a program called Creeper that could infiltrate a computer network. At the time, computers were connected through phone lines. Companies still assumed they could protect their systems by securing physical hard drives.<\/p>\r\n Many professionals hold that Thomas invented modern cybersecurity. On his heels, Ray Tomlinson used Thomas's findings to create the first computer worm. Tomlinson, who invented email, also created the first antivirus program by coding software to block the worm.<\/p>\r\n Today, large companies often face data breaches. Well-known corporations like Yahoo, Facebook, and Marriott have all experienced major breaches.<\/p>\r\n Information security analysts must stay up to date on the latest hacking innovations so they can protect their organizations.<\/p>\r\n\r\n An information security analyst protects company data from malicious attacks like malware, phishing, and DNS tunneling<\/a>. They analyze network traffic to identify threats or security breaches and strengthen the network against future attacks.<\/p>\r\n Cybersecurity analysts work with other IT members to install and maintain a secure network. For example, they may collaborate with software developers to improve current encryption programs or partner with database administrators to create stronger networks. Security analysts also work with company staff, educating them on new security measures.<\/p>\r\n While other computer science roles create software or communication networks, security analysts focus on information security. They act as digital detectives, searching for malicious activity.<\/p>\r\nHistory of Information Security Analysts<\/h2>\r\n
