Malware Trends for 2015 and What Companies Can Do

Within the past year, Kivu has seen several malware trends emerging, including exploitation in widely used software applications (Heartbleed, Bash, and Shellshock), cycles of ransomware and destructive malware (Master boot wiper, HD wiper), and an increase of rootkits, botnets and traditional drive-by malware. In 2015, we expect to see new malware trends, including an increase in social engineering (attack the weakest link), exploitation of identified security flaws in newly developed mobile payment applications, exploitation of cloud SharePoint systems, and the continuation of exploitation of traditional Point of Sale (POS) credit card systems. Kivu also expects an increase in exploit kits for all types of mobile devices and traditional devices that contain diverse functionality.

Following is what Kivu recommends that companies do to help secure their systems and data.

Protecting Your Computer Environment Against Malware

To protect your environment, Kivu recommends a strength-in-depth approach, coupled with segmentation of sensitive data. Segmenting your network environment adds an additional security layer by separating your sensitive traffic from other regular network traffic. Servers with PHI, PII or PCI should be segmented from the backbone and WAN. A separate firewall should protect this segmented data.

Ensure that your firewall is fine-tuned, hardened, and that vital security logs are maintained for at least 2-3 months. Conduct regular external and internal vulnerability network scans to test your security perimeters and detect vulnerabilities. Remediate these security flaws within a timely manner.

Perimeter protection devices require regular maintenance and monitoring. Ensure that your ingress/egress protection devices (IDS/IPS) are monitoring real time to detect malicious network traffic.

Be sure to maintain and update your software and system applications on a regular basis to eliminate security flaws and loopholes. Verify that all security applications within your environment are fine-tuned and hardened and that security logs are maintained. Review your security logs on a regular basis to ensure that logging is enabled and that valid data is being captured and preserved for an extended time period without being overwritten.

Remote Access Considerations

Kivu recommends limiting and controlling remote access within your environment with two-factor authentication. Create a strong password policy that includes changing passwords frequently and eliminating default passwords for systems and software applications that are public facing.

For outsourced IT services, make sure your data security is in compliance with the latest standards and policies. Maintain and verify on a regular basis that all 3rd party vendors follow outlined security policies and procedures. Eliminate account and password sharing and ensure that all 3rd party vendors use defined and unique accounts for remote access.

Securing Vulnerable Data

Protecting your data is not only the responsibility of Information Security; it is everyone’s responsibility to do their part to keep your environment safe and secure. Encrypt, protect and maintain your critical data. Upgrade older systems when possible and verify that sensitive data is encrypted during transmission and data storage. Manage and verify data protection with all 3rd party vendors.
