Security administrators are key members of cybersecurity teams that work to protect organizations' computer systems. Like many other cybersecurity careers, the well-paid role remains in high demand.

Cybersecurity Ventures reported a 350% increase in vacant cybersecurity jobs from 2013-2021. Their findings also noted a critical shortage in the United States, which has generally led to increased pay rates for qualified professionals.

This guide explores a typical day in the life of a security administrator in detail. The following sections focus on day-to-day security administrator duties, along with common job settings and tips on how to enter this fast-growing career path.

What Is the Job Description Of a Security Administrator?

Hacking and other forms of unauthorized system access have been a part of computing since its earliest beginnings. The cybersecurity field began to emerge in the 1970s as a response to these attacks. At the time, computer technology was developing quickly, and many businesses and government agencies had adopted security efforts.

The security administrator role evolved as cybersecurity matured into an important field. Security administrators hold mid-level positions on cybersecurity teams. Most of their duties revolve around setting up, managing, and updating their employer's cybersecurity tools.

In some settings, security administrators are the next level up from security analysts. In smaller organizations with fewer people on their cybersecurity teams, administrators may also perform analyst tasks.

Security administrator positions sometimes appear under other names, like network security engineer or security specialist. They are also called information security managers and information systems security officers.

What a Security Administrator Does

In most cases, a security architect designs an organization's cybersecurity systems and policies. Security administrators may help with design duties, but they generally implement the strategies created by team leaders.

CompTIA describes security administrators as entry-level or mid-level cybersecurity team members. They primarily install and manage the technical tools in their employers' cybersecurity programs. Security administrators also troubleshoot and correct issues with these tools, write policy documents, and train other employees to follow best practices.

Successful security administrators share several qualities that serve other cybersecurity professionals, as well. These include advanced technical knowledge, sound ethics, and a commitment to ongoing learning and development. Security administrators also require strong attention to detail and problem-solving skills.

The day-to-day of a security administrator, described in detail in the section below, also poses challenges. Their work often involves long, stressful workdays. The ongoing shortage of cybersecurity workers also forces many employees to take on extra duties.

Main Duties of Security Administrators

Installing and Maintaining Cybersecurity Tools: A typical day in the life of a security administrator often involves setting up cybersecurity software and equipment. These tools include antivirus programs, user authentication systems, firewalls, and security patches. Security administrators also update these devices and troubleshoot them when bugs or problems occur.

Checking for Vulnerabilities: Security administrators often assist other team members in their system monitoring duties. They probe systems and networks for vulnerabilities. Security administrators may perform more of these tasks in companies with smaller teams.

Network Traffic Monitoring: In smaller companies, security administrators hold fluid positions involving more analysis duties. They may actively oversee network traffic for signs of unusual or potentially hostile activity.

Creating Security Policies: A security administrator's job description often includes duties related to security policy. Security administrators develop security policies alongside other, more senior team members. They also write policy documents and supervise non-technical staff members to ensure they follow best practices.

Training Colleagues: Some security administrators have more advanced technical profiles. In these cases, security administrators often train coworkers in safe and proper use. Security administrators also provide colleagues with general cybersecurity awareness and education.

Nonstandard Duties for Security Administrators

Continuity Planning: Organizations create formal plans to prepare for major disruptions or disasters. In the age of digital technology, cybersecurity team members have played key roles in response efforts. Some security administrators offer input, especially regarding cyberattack recovery.

Security Auditing: Companies perform security audits of their systems and networks by reviewing information security systems, tools, policies, and strategies. Some security administrators set up automated auditing tasks and perform manual system checks. These duties may also include writing reports explaining their findings.

Advising Non-Technical Decision-Makers: Members of middle and upper management who work in non-technical roles sometimes need to make decisions that affect technical operations. They may consult team members with technical expertise as a part of the decision-making process. Some security administrators occasionally take part in these consultations.

Writing Performance Reports: Some security administrator job descriptions include preparing reports on situations affecting network status or performance for technical and non-technical personnel.

Continuing Education: Cybersecurity threats constantly evolve, and new cyberattack vectors develop as technology advances. Professionals need to stay on top of the latest techniques used by malicious actors and develop the skills needed to address them.

A Typical Day for a Security Administrator

A typical day in the life of a security administrator differs based on the employment setting. Some administrators hold full-time positions in companies or public-sector agencies. Others work for technical consulting firms and engage with many clients over a day.

A security administrator working full-time for a single employer often spends much of their day on technical tasks. These duties mainly include developing, testing, maintaining, and updating security tools. Security administrators may also monitor traffic alongside security analysts.

Some security administrators double as analysts in smaller organizations with limited cybersecurity budgets. In these cases, administrators spend more time on analytical tasks like traffic monitoring and vulnerability testing.

Administrators working for consulting firms often spend most of their time on infrastructure tasks in server environments. These professionals mainly work remotely to service clients' system monitoring and information security needs.

As with many other cybersecurity roles, security administrators often work long hours. Atypical work hours may also factor into their daily duties, typically for administrators who work for consulting firms in different time zones.

Where Security Administrators Work

The U.S. Bureau of Labor Statistics (BLS) groups security administrators in its category of information security analysts. According to the BLS, information security analysts' top industries of employment in 2020 were:

  • Computer systems design and related services accounted for 26% of the 141,000 U.S. infosec analyst jobs
  • Finance and insurance (18% of jobs)
  • Information (10%)
  • Enterprise management (9%)
  • Administrative and support services (5%)

The BLS also tracks the percentage of information security analysts working in specific industries. From this viewpoint, the top five U.S. industries as of May 2021 were:

Meanwhile, BLS geographic profiles for infosec analysts cited these five states as the top employers as of May 2021:

Notably, Virginia and Maryland are close to Washington, D.C. This reflects the large numbers of information security professionals working for federal agencies. The public sector is a major employer of security administrators and other cybersecurity specialists.

Private-sector employers engaged in activities involving large volumes of sensitive data also have increased cybersecurity needs. In addition to financial services firms, these also include healthcare and education organizations.

Should You Become a Security Administrator?

A typical day in the life of a security administrator can be demanding. People who succeed in the role are passionate about their work and committed to ongoing professional development, which may include earning relevant certifications.

Security administrators hold mid-level roles in cybersecurity teams. Many administrators advance into their positions after gaining experience in entry-level roles.

Cybersecurity careers attract candidates because of the high pay and strong demand. They may fail to realize the extent of technical knowledge and work required for success in the sector.

If you are tech-savvy with a knack for designing solutions to complex problems, then a career in cybersecurity may be a good match. However, remember that the role may include high-stress work with long days.

How to Prepare for a Career as a Security Administrator

Aspiring security administrators can follow multiple paths to prepare for their careers. Employers' requirements vary, but many prefer or require degrees in computer science or related fields for entry-level jobs.

An associate degree may open doors to some roles. However, companies often look for applicants with bachelor's degrees or higher when filling positions with advancement potential.
