What is Operational Security (OPSEC) and How Does it Protect Critical Data?

By Veritis

Operational Security

Operational security (OPSEC), also known as procedural security, was created by the US military during the Vietnam War. This application is widely used in business as a risk management plan for preventing sensitive data without malicious intent. OPSEC is a plan that challenges IT and security pros to look at their operations and systems from the view of a hacker. It includes analytical tasks and procedures such as social media, behavior monitoring, and security best practices.

OPSEC aims to close all security holes that allow threat actors to steal sensitive data from an organization. Robust security isn’t about having the proper hardware or software; it’s about knowing exactly how they work and where the gaps are. When used alone, not every type of information is regarded as sensitive. However, if a hacker combined this data, they could use it for different things, such as creating convincing phishing emails or accessing user accounts.

Raising awareness of this problem can be challenging. The OPSEC approach will produce a framework for adopting policies and best practices. Whether an organization can set guidelines for employees depends on the detected vulnerabilities and threats to its business. This blog post will explain OPSEC’s five steps and best practices.

What is OPSEC?

What is Operational Security

OPSEC is a military term for plans to prevent potential enemies from learning important information about operations. This concept has transferred from the military to other branches of the federal government, including the Department of Defense (DOD). OPSEC plans are now used in corporate operations as information management and protection, which have become crucial to success in the private sector.

OPSEC is all about securing sensitive information in an organization. It employs specific governance techniques to manage risk continuously. Your enterprise uses OPSEC daily, even if you aren’t aware of it. The OPSEC process can be as easy as placing a firewall between your system and the Internet to aid in the securement of information and ensure the proper disposal of hard copies.

Before you can deploy OPSEC security, you must determine the location and type of your storage. OPSEC keeps information in two categories: tacit and explicit. In terms of a company’s productivity, both are significant liabilities. The OPSEC process helps businesses address corporate data, information security, and risk management. It is employed by a company keen to safeguard its valuable data.

Importance of Operational Security

Recognizing the importance of Operational Security (OPSEC) is crucial for organizations safeguarding their financial well-being. By implementing rigorous OPSEC measures, organizations can prevent significant monetary losses from security breaches. Strong OPSEC offers several key benefits:

  • Safeguarding Against Intellectual Property Theft: Prevents competitors from gaining access to proprietary processes or technologies, preserving the original innovators’ market advantage and revenue generation.
  • Mitigating Legal Expenses: It reduces the risk of lawsuits from data breaches that compromise customers’ personal information and limits potential fines for non-compliance with industry regulations such as GDPR or HIPAA.
  • Prevention of Ransomware-related Costs: This product protects against malware and ransomware attacks that could encrypt critical systems and demand substantial ransoms for decryption keys.
  • Minimizing Costs Associated With Business Disruption: Reduces downtime resulting from cyber-attacks, which directly translates to diminished productivity and sales.

The 5 Key Steps of Operational Security

The 5 Key Steps of Operational Security

The five steps combined in the OPSEC process allow companies to secure their data processes.

1) Detect Your Sensitive Information

The first critical step in ensuring OPSEC security is understanding businesses’ data and the sensitive information they maintain on their systems. This includes detecting user information such as client’s data, financial information, employee details, and intellectual property. Companies need to concentrate their resources on protecting this essential data.

2) Detect Possible Threats

The next stage is to identify the potential threat matrix to your business. Companies must assess the potential threats once the sensitive data has been recognized. Identifying who can pose a severe threat allows you to evaluate the risk depending on the skill set of the possible opponent.

3) Analysis of Vulnerabilities and Other Security Holes

This is a critical step in the information risk management process. The business must scour any security gaps that might allow threats to be displayed. Assess the current condition of your security to detect flaws that could be exploited to access your sensitive data. This should combine software and hardware security solutions, including automated security patch updates, employee awareness and training, and best practices like 2FA and strong passwords.

4) Assessment of Threat Level

The following step is to ascertain the threat level connected to most discovered vulnerabilities. Next, the organization ranks the risks depending on the factors, including the likelihood that a given assault would occur and the impact such an attack would have on operations. The system’s low, medium, or high threat level is determined.

5) Create a Strategy to Eliminate these Threats

This data allows companies with everything necessary to create a strategy to eliminate the threats detected. The last step in OPSEC security is implementing countermeasures to eliminate threats and reduce cyber risks. These frequently involve developing policies for protecting sensitive data, upgrading hardware, and training staff members on security best practices and corporate data regulations.

Best Practices for OPSEC

Best Practices for OPSEC

OPSEC process steps apply risk management plans to detect potential threats and vulnerabilities before they are abused and pose business issues. A company can build and implement an effective and robust security plan by following the six best practices.

1) Implement Specific Change Management Techniques

Companies must put the right change management plans in place for staff members to follow in case network modifications are performed. All modifications must be controlled and managed so companies can audit and monitor the alterations.

2) Deploy Least Privileged Access to Network Devices

Allow the least access to network devices using authentication, authorization, and accounting (AAA). Employees must have the minimum access to resources, networks, and data to operate successfully. This involves applying the least privilege principle, which ensures that every program, process, and user has the minimal privileges necessary to carry out their tasks.

3) Implement Dual Control

Organizations must verify that the teams and individuals who manage security differ from those who work on your network. This strategy protects against issues like conflicts of interest and others.

4) Automation

Regarding business security, people are often the weakest links for data. In addition, human errors can result in detailed mistakes, critical processes, and forgetting things. Automation can reduce these errors.

5) Use Strong Passwords, 2FA and VPNs

Data breaches frequently result from human error. It would help if you verified that strong passwords and two-factor authentication (2FA) are used on every user account and trained employees on potential phishing threats. VPNs should be used while transferring data or working remotely to ensure the data is securely encrypted.

6) Disaster Recovery Planning and Incident Response

Solid disaster and incident response plans are vital components of any security defense. Even with operational solid security measures, you still need a plan for identifying risks, dealing with them, and mitigating the potential risks.
