CACI Careers Uncovered: Essential Skills for Defense Cybersecurity Jobs
The Growing Demand for Cybersecurity in Defense
The digital world of defense organizations has changed dramatically over the last several years. Sophisticated cyber actors can now exploit vulnerabilities to steal sensitive information, disrupt essential services, and potentially cripple national security infrastructure. The stakes have never been higher.
Why Defense Cybersecurity is More Critical Than Ever
Defense agencies worldwide face unprecedented challenges as cyber threats don’t fit neatly into traditional security frameworks. Organizations faced an alarming average of 1,158 weekly cyberattacks in 2023—a 1% increase from the previous year. This constant assault on defense systems has pushed governments to spend more on cybersecurity.
Money tells the real story. Global cybercrime costs will grow by 15% each year and reach $10.5 trillion by 2025—up from $3 trillion in 2015. Governments now spend unprecedented resources to curb these threats. The U.S. Department of Defense’s AI contracts jumped from $190 million in August 2022 to $557 million just one year later.
More than half of the world’s critical infrastructure organizations report being hit by large-scale cyber attacks or infiltrations. These attacks target government systems, defense contractors and private companies that support military operations. The SolarWinds attack showed how vulnerable even the most secure networks can be when it breached numerous government agencies through compromised software updates.
The expanding Internet of Things (IoT) has created more opportunities for cybercrime. Experts estimate 64 billion IoT devices will be installed worldwide by 2026. This growing interconnectedness makes defense systems more vulnerable to sophisticated attacks.

8 Must-Have Skills for CACI Cybersecurity Jobs
CACI needs cybersecurity professionals who excel at specialized skills and technical expertise to protect our nation’s defense systems. The company looks for candidates with detailed skills to curb sophisticated cyber threats as the landscape keeps evolving.
1. Network Defense and Monitoring
Defense networks need constant alertness and deep knowledge of security technologies. CACI’s cybersecurity engineers set up and run critical systems like firewalls, intrusion detection/prevention systems (IDS/IPS), and security information and event management (SIEM) tools. They study network traffic logs to spot vulnerabilities, handle cyber events, and build stronger defenses against attacks on network infrastructure.
2. Malware Analysis and Reverse Engineering
Breaking down malicious code shows how attackers work. Defense cybersecurity experts should know malware functions, delivery methods, and their effects. CACI values professionals who can handle both static analysis (code review without running it) and dynamic analysis (watching malware behavior in controlled settings). These skills help spot patterns in malware families and speed up responses to new threats.
3. Penetration Testing and Vulnerability Assessment
Defense systems stay secure by finding weaknesses before attackers do. CACI’s penetration testers run detailed security checks using OSCP, GPEN, and GXPN methods. They test web applications, networked devices, and standalone software to find weak points that could put critical defense infrastructure at risk.
4. Secure Software Development
Security belongs in applications from day one to stop vulnerabilities. CACI’s DevSecOps approach puts security at every step of software development. Engineers use secure coding practices, set up proper authentication, and review code carefully to prevent security flaws.
5. Cyber Threat Intelligence
Knowledge of adversaries’ tactics, techniques, and procedures (TTPs) keeps systems safe. CACI’s cyber intelligence analysts track new threats, monitor unauthorized activity, and link suspicious behavior across networks. They turn technical findings into applicable information that shapes defensive strategies and operational choices.
6. Incident Response and Recovery
Quick action limits damage when breaches happen. CACI’s incident responders handle everything from detection and first analysis to response planning and follow-up reviews. Their expertise helps organizations contain threats, remove malicious elements, and get back to work quickly.
7. Risk Assessment and Compliance
Smart risk management balances security needs with operations. CACI’s security engineers check systems against NIST 800-53, RMF, and CMMC standards. They create System Security Plans (SSPs), check for risks, and make sure defense systems follow strict regulations.
8. Cloud and Hybrid Infrastructure Security
Defense organizations moving to cloud solutions need robust security measures. CACI’s cloud security specialists use zero-trust approaches, control data flows between environments, and ensure encrypted communications. They work with both traditional security and cloud-native controls to keep hybrid systems safe.
How to Build These Skills Before Applying
A career in defense cybersecurity demands strategic skill development. Your expertise in multiple areas will make you stand out as a candidate for CACI’s cybersecurity roles.
Certifications that Matter (e.g., CISSP, CEH, Security+)
Industry-recognized certifications validate your cybersecurity knowledge effectively. CompTIA Security+ creates an excellent foundation for defense positions and meets DoD 8570 requirements. Advanced certifications like CYSA+, CISSP, or CEH showcase deeper expertise. CACI’s job listings specifically highlight these credentials as preferred qualifications.
Hands-On Labs and Simulations
Theoretical knowledge alone isn’t enough – practical experience matters significantly. SANS Cybersecurity Labs create immersive scenarios that let you analyze data from real compromises. These environments help you develop job skills through authentic defense scenarios. Platforms like TryHackMe and Hack The Box offer gamified labs aligned with MITRE ATT&CK and NIST frameworks.
Open-Source Practice Tools
Free security tools showcase your initiative and practical skills. Here are some essential tools:
- Wireshark for network protocol analysis and traffic monitoring
- Metasploit for vulnerability testing and exploitation
- Kali Linux distribution with pre-packaged security utilities
- Nmap for network discovery and security auditing
