MDR Partner: Responding to cyber security threats in 2023
Having detection capabilities is not enough, businesses need to be able to respond to cyber threats. In today’s digital age, the threat of cyberattacks is a real and constant threat to businesses of all sizes. SMBs in particular are at a disadvantage due to lack of cyber capabilities. Turning to a MDR partner such as HostBreach is an ideal option to outsource these concerns. Cybercriminals are constantly evolving their tactics and techniques to infiltrate corporate networks, steal valuable data, and disrupt operations. To effectively respond to these threats, organizations must have robust and comprehensive security response plans in place. This article explores four key strategies for responding to cyberthreats: using DNS sinkholes, resetting account credentials, isolating endpoints, and restoring business-critical data from backups.
DNS sink-hole
DNS sinkholing is a technique used to block access to malicious websites and prevent malware from communicating with command and control (C&C) servers. This involves redirecting traffic from malicious domains to non-existent or controlled domains, effectively disrupting communication between the malware and its C&C server. Organizations can use this technique to prevent malware from spreading through networks and stealing sensitive data.
Reset account credentials
Another important cyberthreat response strategy is resetting account credentials. In the event of a compromise, it is important to reset the compromised account credentials immediately to prevent further unauthorized access. This includes not only passwords, but also usernames, security questions, and other authentication mechanisms that may have been compromised. Additionally, organizations should implement regular password change policies and use two-factor authentication to further strengthen their security posture.
Isolate endpoints
Endpoint isolation is another key strategy for responding to cyberthreats. Isolate infected or compromised endpoints from the rest of your network to prevent the spread of malware and other threats. Isolation can be achieved by physically disconnecting the device from the network or by using software tools to isolate the device and prevent it from communicating with other devices on the network. EDR tools such as the Elastic agent can isolate the endpoint so that it can only talk back to the EDR platform for further analysis.
Restore business-critical data from backups
Finally, organizations should be prepared to recover business-critical data from backups in the event of a cyberattack. Backups are essential for recovering lost or stolen data and also help minimize downtime and business disruption. It is important to regularly test and validate your backups so that they can be used effectively in the event of a disaster.
In summary, cyber threats are a constant threat to organizations, but with a good security response plan,organizations can effectively mitigate these threats. Strategies such as using DNS sinkholes, resetting account credentials, isolating endpoints, and restoring business-critical data from backups are integral partsof an effective security response plan. By implementing these strategies, organizations can reduce the risk of cyberattacks and minimize the impact of successful attacks. Contact HostBreach, a MDR partner for questions.
