MOS 25D Requirements: Qualifications and Skills
In order to become a MOS 25D, there are a few requirements you need to acquire:
Qualifications
ASVAB scores must be valid at the time of application to qualify for consideration. A 105 score on the General Technical and Skilled Technical are required.
Self-discipline and intelligence

These are traits that Army Cyber Network Defender (MOS 25D) must have in order to succeed in the demanding career. This is because they serve as the leaders of the Army’s cyber defense operations, protecting classified information and systems across Military networks while also operating within strict ethical standards. MOS 25D must be confident and self-disciplined enough to make decisions and exercise discipline in a variety of situations. It matters not whether you are a computer science expert or just looking for a new career; if you possess these skills and qualities, this may be your chance to be part of something big.
Army Cyber Network Defenders spend most of their time at computer terminals. They must have great attention to detail in order to analyze online traffic and recognize potential problems quickly so they can stop attacks before they do harm. They must also exercise discretion in every aspect of the job, from handling confidential information to handling correspondence with collaborators in other countries who may have different goals than those of the U.S. Army.
Advanced Threat Knowledge

These Soldiers must be able to understand how threats will change over time and anticipate threats before they develop. They must be able to maintain a sense of security in a world where people are growing increasingly aware of their digital footprint. The interconnectedness between systems and their reliance on the internet to work allows hackers around the world to access U.S. military networks.
Physical and mental fitness
Commanders and leaders must be physically and mentally fit to lead in combat operations. More than that, they must be able to control their emotions and keep a cool head when under extreme pressure. This is how they maintain their composure and make rational decisions under stressful conditions. These traits come together to make the perfect leader: The Army Cyber Network Defender might go to work in the middle of the night, when people are least likely to be using computers or on weekends. They are required to complete many hours of training in addition to normal work responsibilities. The demand for qualified cyber defenders has increased significantly in recent years. With the threat of cyber-attacks on our nation’s critical infrastructure and military systems growing annually, these soldiers must remain confident and collected during this high-pressure environment.
Adhere to ethical standards and attention to detail
It’s important for leaders not only to be physically fit but also smart enough to do their job effectively; this is what matters most at the end of the day. Maintaining optimal attention makes it easier for them to notice developments quickly, ensuring there is no time wasted during crucial moments like combat situations or thus allowing them more time for planning an operation. As a leader, you must be aware of the fact that your actions represent not only yourself but also the organization you work for. Therefore, you must make sure that everything you do is in line with the ethical standards expected from an Army Cyber Network Defender (MOS 25D). This will ensure that the public’s trust in you remains intact.
Job Responsibilities
The Army Cyber Network Defender (MOS 25D) is responsible for defending Army networks and information systems against cyber-attacks and intrusions. The Army Cyber Network Defender (MOS 25D) ensures the security and availability of all Army computer networks, information systems, applications, and databases by identifying vulnerabilities through risk assessments, network monitoring & analysis tools, vulnerability scanning tools, intrusion detection mechanisms such as honeypots or IDSs as well as countermeasures such as firewalls to respond to attack or intrusion attempts.
Knowledge and Expertise

The MOS 25D will also be required to learn other information systems security skills to include but not limited to Memory Analysis, Binary Analysis, Rootkit Analysis, Software Reputation Systems, Data Loss Prevention (DLP), Anti-Phishing, Anti-Malware Systems, and Privileged User Monitoring.
Hardware and software testing

As an Army Cyber Network Defender, your primary role is to provide 24 hours a day, 7 days-a-week analysis of the network. This includes monitoring the network for any suspicious activities and conducting vulnerability testing. Once any potential threats are detected by you, your team will work on mitigating the threat while preserving the integrity of information systems and networks. You will also be in charge of implementing new hardware or software solutions that will allow you to monitor cyber events more easily. Also, when something goes wrong with the network (i.e., core infrastructure core stops working, etc.), you will be the one to repair it quickly.
You will also be responsible for implementing any new hardware or software that can help keep the network safe. This includes things like new firewalls, intrusion detection systems (IDS), intrusion prevention systems (IPS), anti-malware programs, and even new network devices that perform other specialized tasks.
Respond to crisis or urgent situations

Due to its highly critical nature, Army Cyber Network Defender is often called upon to help protect networks from a variety of cyberattacks. In the event of a potential crisis, you will be able to calm your team members by using your communication training to assure them that you have a plan of action. You will then use your technical knowledge to formulate a protocol that will help find and terminate the threat. Some of the threats you might face include Denial-of-service attacks, viruses, worms, and Trojans. As an Army Cyber Network Defender, you must always be prepared for a crisis since it is a highly stressful environment. You will often find yourself under the sound of gunfire.
Identify suspicious report events

As an Army Cyber Network Defender, your team will be able to use all available resources (i.e., Information Intelligence) to inform them about anything that might undermine the security of their information systems and networks (i.e., vulnerabilities). For example, you might find out that three different operating systems are vulnerable to attacks by adding one software package to it; this will be relayed back up to your fellow defenders for further analysis. You will then use this information to plan defensive actions that will ensure the integrity of your network.
You will also receive alerts about any cyber-attacks involving your network. Through analysis of your alerts, you will be able to identify the nature of the attack. Some of the information included in these alerts is details regarding which type of attack is being used, an analysis of how it works and how it gets into your network, etc.
