Operational security, or OPSEC, is a field of study that takes possible threat actors into account. IT teams and security managers may find and address risks and weaknesses with this proactive approach to security before criminals can take advantage of them.
Although OPSEC was first created for military organizations, procedures are now being implemented by many enterprise industries to safeguard their most sensitive data from potential attackers. Companies are forming OPSEC teams in order to better manage security risks rather than waiting for an event to occur.
What does operational security entail, and how can your company begin using it? You can implement eight practices to assist your organization in developing its OPSEC program.
What is OPSEC?
Operational security (OPSEC) is a procedure for risk management and security that keeps private data out of the wrong hands.
It is also a method that finds seemingly innocent activities that can unintentionally give sensitive or important data to a cybercriminal. OPSEC encourages IT and security managers to see their operations and systems from the standpoint of a possible attacker. It is both a process and a strategy. Additionally, it consists of analytical procedures and activities such as social media monitoring, behavior tracking, and best practices for security.
Furthermore, using risk management to identify possible risks and weaknesses in an organization’s operations, processes, and employee-owned gear and software is a critical component of OPSEC. OPSEC teams can find problems they may have missed by viewing systems and operations from the perspective of a third party. This perspective can be vital for putting the right countermeasures in place to protect their most sensitive data.
What are the five steps of OPSEC?
OPSEC consists of five phases that help enterprises safeguard their data processing.
#1. Identify sensitive data.
One of the most important initial steps in OPSEC security is to understand what data an organization has and the sensitive data it stores on its systems. This includes identifiable data like credit card numbers, employment information, financial documents, customer information, intellectual property, and product research. It is imperative that companies concentrate their efforts on safeguarding this crucial information.
#2. Identify possible threats.
After identifying the sensitive data, companies must ascertain the possible risks that could compromise this information. This covers outsiders who would seek to obtain access to the data, rival businesses who might benefit from information theft, and malevolent insiders such as dissatisfied staff or careless personnel.
#3. Analyze the vulnerabilities.
The next step for organizations is to assess any weak points in their security measures that can allow the threats to become real. This entails evaluating the technological solutions and procedures that protect their data and locating any vulnerabilities that an attacker might be able to take advantage of.
#4. What is the threat level?
The next step is to assign a threat level to each vulnerability that has been found. The chance that an attacker will target a vulnerability, the degree of harm that can result from its exploitation, and the time and effort needed to mitigate and restore the damage should all be taken into consideration when ranking vulnerabilities. Therefore, organizations should prioritize and allocate more resources towards risk mitigation, the greater the potential damage and likelihood of an attack.
#5. Devise a plan to mitigate the threats.
Organizations can use this information to create a plan that will mitigate the hazards that have been identified. Installing countermeasures to get rid of threats and lessen cyber hazards is the last phase of OPSEC. These usually include giving staff training on security best practices and corporate data regulations, updating hardware, and developing policies for protecting sensitive data.
Note that an OPSEC process plan needs to be easy to comprehend, easy to follow and implement, and flexible enough to be revised when the landscape of security threats changes.
OPSEC Best Practices
To put into place a strong, all-encompassing operational security program, adhere to these best practices:
- Establish clear change management procedures that staff members must adhere to when making network changes. To enable monitoring and auditing, all changes ought to be recorded and managed.
- Limit network device access by employing AAA authentication. A “need-to-know” premise is frequently applied as a general guideline for information access and sharing in the military and other governmental institutions.
- Give your staff the minimal amount of access they need to do their duties. Apply the least privilege principle.
- Put dual control in place. Verify that the individuals working on your network are not the same ones handling security.
- Reduce the need for human intervention by automating tasks. Because people make mistakes, forget things, ignore subtleties, and circumvent procedures, they are the weakest link in any organization’s operational security initiatives.
- Disaster recovery planning and incident response are always essential parts of a strong security posture. You need to have a plan in place to recognize hazards, address them, and lessen any possible harm, even with strong operational security measures.
Note that being able to recognize risks and vulnerabilities before they materialize into issues is essential to risk management. Operational security compels managers to examine their operations in great detail and identify any weak points at which their data may be compromised. Managers can identify vulnerabilities they might have otherwise overlooked and put the right countermeasures in place to secure sensitive data by viewing operations through the eyes of a malevolent third party.
What is OPSEC certification?
OPSEC PROFESSIONALS SOCIETY (OPS) CERTIFICATIONS
The ability to get the professional status of OPSEC Associate Professional (OAP) or OPSEC Certified Professional (OCP) is one of the main advantages of joining the OPSEC Professionals Society. Colleagues and employers can know more about your degree of skill in the field by using the OCP or OAP proficiency designator after your name.
What is the purpose of the OPSEC program?
Operational security (OPSEC) is a risk management strategy that encourages looking at operations from the standpoint of an adversary. In order to stop sensitive information from being misplaced, stolen, or hacked, it is important to recognize potential vulnerabilities and take appropriate action.
Why is OPSEC for everyone?
OPSEC is for everyone because it can help you keep confidential data out of the hands of adversaries by restricting access to the information. Note that identifying the data that may be compromised should come first, followed by actions to lessen the likelihood of this data being exploited.
What are the responsibilities of OPSEC?
The responsibility of OPSEC is to stop, or at least restrict, the transfer of sensitive, unclassified information to hostile forces. Information security program controls and procedures bear the responsibility for the information’s real content, whether it is classified or not.
What is an example of OPSEC security?
An example of OPSEC activities includes keeping an eye on social media habits and behaviors and forbidding staff members from sending or receiving login credentials by text or email.
Who is responsible for OPSEC?
The NCSC (National Cyber Security Centre) carries out the duties and responsibilities of the National Operations Security (OPSEC) Program Office and supports departmental and agency execution of OPSEC programs.
What are the rules for OPSEC?
The rules of OPSEC are:
- Don’t post your service member’s exact job online;
- Don’t disclose the mission of assigned units;
- Don’t disclose deployment dates and locations;
- Don’t disclose your service member’s precise location overseas;
- Don’t disclose anything regarding equipment or unit morale.
What is the first law of OPSEC?
The First Law of OPSEC: Know the Threats
How can you defend sensitive information against dangers if you are unaware of them? For instance, if a business produces soft drinks, knowing the recipe in secret is vital knowledge. The danger also comes from the secret recipe being revealed to the public.
What is the most important characteristic of OPSEC?
The fact that OPSEC is a process is its most significant feature. OPSEC is not a set of precise guidelines and directives that are applicable to each and every operation. It is a technique that can be used in any operation or activity to keep an enemy from learning vital information.
What is OPSEC in cybersecurity?
Operational security (OPSEC) in cybersecurity is a procedure used by businesses to make sure that private information doesn’t end up in the wrong hands. OPSEC finds activities that appear harmless but might unintentionally expose or leak private or sensitive information to a possible attacker.
What are the five steps to operational security?
The five steps of operational security are:
- Identify sensitive data.
- Identify possible threats
- Analyze security threats and vulnerabilities
- Appraise the threat level and vulnerability risk
- Devise a plan to mitigate the threats
