Unfortunately, 70% of organizations which have established controls to manage changes in their IT infrastructures, bypass security policy requirements and unable to provide preventative actions in time. This increases the risk of data breaches and undermines the viability of companies’ own security policies. In the wave of cyber security breaches, here are five steps to take that will help you ensure that the security policies in your organization are actually followed.
Step 1. Identify the scope of secured data
Advanced attacks happen in a complex and unobtrusive manner. Almost every information in your organization requires additional security measures. Defining what types of sensitive data need advanced protection will solve three major issues: improving visibility, avoiding overload of employees and reducing costs of hardware and software.
Tip: Consider segmenting the environments and implement additional measures of control only for those types of data that actually need it, start from the most business critical IT systems (i.e. Active Directory and file shares).
Step 2: Refer to compliance regulations
When the whole picture is made over and the actions that should be undertaken are planned as sequence of steps, compare your own security policies with those that are recommended by the compliance regulators.
Tip: Detailed and well-structured compliance standard, such as PCI DSS, contain useful tips on what to look for and how to enhance existing security procedures.
Step 3: Monitor user activity
Monitoring is the best way to prevent the cyberattack. Each moment that is lost between awareness and action could cause a data loss and financial threat to your organization. Moreover, insider misuse is fairly judged as the most dangerous type of malicious activity, and is extremely hard to track.
Tip: Companies should look carefully after the users with advanced privileges and immediately react to any suspicious burst of activity like granting inadequate permissions or bulk file copying or modifying.
Step 4: Minimize human factor
Since the human factor is a primary root cause of many data breaches, employees should be familiar with security policies and have a clear understanding of their role in case of a violation.
Tip: Train you employees with detailed instructions of how to deal with sensitive data and explain what steps should be taken, if they spot malicious activity or suspect unauthorized data disclosure.
Step 5: Learn on mistakes
There’s no universal lessons to ensure network security although if a security incident has happened, the best thing you can do is to ensure that it will never repeat. Perceive it as a penetration testing and thoroughly investigate into the case.
Tip: Even if security violation didn’t lead to a security breach, finding the exact root cause will help you to close the gaps and strengthen your cyber security.
No matter the size or industry, companies need to ensure that their internal regulations are permanently adjusted according to today’s fast-paced business environment along with the evolving forms of cybercrime. A consistent security approach in together with the advanced network security solution will protect the sensitive data of clients and stakeholders’ assets.
