Businesses would want to know the extent of data compromise and the vulnerability that was exploited- after a breach has occurred. This data assists them in determining whether or not they need to warn users that their data has been breached and how to protect themselves from the next attack.
The way businesses respond to a data breach and the amount of damage caused by it depends on how well-prepared they are to address these security issues. To begin, organizations need to have the tools and plans in place to conduct an investigation. Proof and timeline analysis are often used to determine how an attacker accessed the network. Knowing how to analyze the evidence and running predictive analysis is critical to a successful investigation.
Strategies that CISOs Can Follow to Minimize the Effects of a Data Breach
Make a communication strategy
Organizations should prepare plans to inform the management of possible threats and risks to the company, as well as plans and resources to mitigate such threats. Meetings must be held on a regular basis to discuss threats and reactions. Furthermore, companies need to identify their core assets and the security mechanisms in place to protect them.
Organizations should also have a plan in place for what to do if a breach occurs. Experts advise that alternative contact methods should be identified, including backup phone numbers and email addresses that are not part of the corporate email or infrastructure, as the email of the company firm may be compromised or affected during the intrusion.
Companies can create a point of contact with local law enforcement in advance. They can take the help of their cyber insurance provider to do so, depending on the size of their business.
Put in place effective access controls
Businesses should document onboarding and offboarding procedures for employees to and from their network services to ensure that permissions and access are correctly set or disabled. Also, it’s a great idea to educate employees on how to properly handle passwords for network access as well as passwords used for specific applications. It is the organization’s responsibility to ensure that no passwords are left in plaintext in file repositories.
Restriction on remote access
Many of the methodologies used by attackers to obtain network access depend on their own remote access methods. The passwords used for entry have most likely been harvested and posted in forums or sold online since they have been used by companies for years.
UAS, the largest hacker marketplace for stolen RDP credentials, recently revealed that the usernames and passwords of over 1.3 million current and previously infected Windows Remote Desktop servers had been leaked.

After gaining access via Remote Desktop Protocol (RDP), attackers can travel around the network laterally, particularly if they have an administrative password. Many servers used vulnerable, easy-to-guess credentials, according to the UAS database, and third-party software often installed default remote access credentials and passwords that could be used by attackers.
Businesses can protect themselves from the possibility of remote access compromise in a number of ways. As the first line of defense, they can restrict remote desktops to unique IP addresses. They can then configure Remote Desktop to use Remote Desktop Gateway as an additional authentication method, as well as use two-factor authentication tools
