What network security methods do I need to keep data safe?

How can you maintain network security beyond the standard firewall and blacklisting tactics? Encryption and digital rights management can ensure organizational data stays safe.

The emergence of complex, multisite, hybrid IT environments has made admins re-evaluate network security and m...

Of course, organizations must still take standard security measures -- such as protecting against unauthorized access or using pattern matching and predictive measures to spot distributed denial-of-service attacks. However, it's easier to protect a network infrastructure today. Orchestration can enable organizations to shut down and replace compromised VMs and containers in a matter of hours.

Today, organizations must focus on protecting their information, which is becoming more valuable. The information created by and stored within an IT environment is the organization's lifeblood. Without the right network security methods, companies can lose documents that contain proprietary information. Malicious actors can also alter financial documents.

Backups can provide new versions of compromised documents. However, when a breach is discovered, it's often too late to protect the brand's reputation.

Network security methods for data protection

Security specialists should focus on network security methods that protect information. These protocols include encryption combined with document classification, data leak prevention (DLP) and digital rights management (DRM).

Selective encryption protects sensitive data against the walled garden effect, where a threat actor connected to simple challenge-and-response systems can go through a network's available information sources. It also minimizes the resources required to manage the encryption/decryption process.

Selective encryption protects sensitive data against the walled garden effect.

DLP captures and ensures data attempting to cross through firewalls or screening software is allowed to do so and blocks potentially malicious activity.

DRM secures information that is no longer under an organization's direct control -- for example, emails that have been sent to the wrong person but not picked up by DLP systems. Information under DRM's jurisdiction must go through a central organizational check to verify the information's recipient has the access required to see the info, as well as what specific permissions they have.

For additional network security methods, admins can install mobile secure gateways, use two-factor authentication for verified access and implement intrusion detection software.
