The phrase cybersecurity is being bandied about across the world’s media. Its main goal is to strengthen the confidentiality, integrity and availability of data, systems and other elements of the information and communication infrastructure. Are you taking all the important precautions?
Segmentation and segregation
Segment your infrastructure into smaller parts and strictly separate user rights across users. This will create zones with different levels of security restrictions and better protect sensitive information and critical services.
Check incoming emails
Are you familiar with Sender ID, Sender Policy Framework, DomainKeys Identified Mail or Domain-based Message Authentication, Reporting and Conformance? They can help you detect the dangers hidden in spoofed emails. If you want to protect your clients as well, it is very important to set up checks for outbound messages as well.
Blacklists/Whitelisting
Block malicious IP addresses and domains at the gateway level (blacklist) or apply whitelisting of web domains. The advantage of whitelisting is a higher percentage of blocked domains.
Monitor and store network traffic
Monitor client-to-server traffic, client-to-Internet traffic, server-to-server traffic, and network perimeter traffic to identify operational and security issues. It is a good idea to keep records of routine network traffic for a minimum of 12 months, with a minimum of 18 months for critical information infrastructure and essential service information systems under the Cybersecurity Act and related regulations.
Check the certificates used
Especially for certificates for SSH authentication, web servers and remote desktop, don’t forget to check the certificates used. Use encrypted communication wherever possible. It will provide greater confidentiality.
Additional recommendations include deploying network detection systems, automated dynamic analysis of email and web content, application firewalls, or centralized and time-synchronized network event logging.
