Ten Cybersecurity Fundamentals to Reduce Your Risk of Attack
Due to escalating tensions with Iran and recent cyber activity against a U.S. Government website, DHS’s Cybersecurity and Infrastructure Security Agency team has issued a bulletin warning organizations to be prepared for “cyber disruptions, suspicious emails, and network delays.” DHS recommends preparing by focusing on “cyber hygiene practices” to defend against the known tactics, techniques and procedures (TTPs) of Iran-associated threat actors. This warning serves as another reminder that adversaries often compromise organizations through failures in assessing and implementing basic security practices.
Based on recent international activities announced by DHS, expectations of retaliation from a known adversarial nation state are more than likely to occur. This is an immediate risk to all public and private organizations in the United States. Organizations need to be able to assess their current security posture and accurately evaluate their cyber hygiene. They need to know what is on their networks, how it is all connected and the risk associated with each asset.
Whether you are hands-on-keyboard technician or an executive responsible for securing your organization, here are ten cybersecurity fundamentals you can implement.
- Identify critical data and where it is housed
- Know what assets – physical and virtual – are on your network
- Harden your network devices, making sure they are securely configured
- Review your endpoint data sources to make sure you have full coverage of all endpoints on your network
- Ensure that your vulnerability scanner is scanning every subnet
- Factor in accessibility to prioritize your highest-risk vulnerabilities and hosts
- Make sure only approved or authorized access is allowed, including any third-party access.
- Validate that all network traffic goes through your security stack(s)
- Identify unnecessary ports and protocols
- Identify rules on your network gear to determine if they are valid and applied appropriately
