- How to protect against WannaCrypt (and other) ransomware?
- Keep your system Up-to-date: If you are using older, but supported versions of the Windows operating system, then keep your system up to date (If you are using LDMS / LDSS or Ivanti Endpoint Manager, see the Patch and Compliance landing page). ==> http://gsurl.in/2XHO
- Unsupported versions of Windows (Windows XP, Vista, Windows 8, Server 2003 and 2008): Microsoft released an emergency patch which can be found here. ==> http://gsurl.in/2XHZ
- Beware of phishing: never open e-mail attachments from an untrusted sender or click on links within e-mails or documents without checking the source. Ivanti Anti-Virus "clikc" ==> http://gsurl.in/2XI2 can also scan incoming e-mail.
- Regularly backup user data: create copies of all user data at regular times to prevent data loss, should a ransomware attack occur.
- Enable Windows firewall: limit the spreading of ransomware within the corporate network by correctly configuring firewalls. Block access to SMB ports over the network and/or the Internet. The protocol operates on TCP ports 137, 139 and 445 and over UDP ports 137 and 138.
- Block legacy protocols such as SMB v1: See the following article on how to enable and disable SMBv1, SMBv2, and SMBv3 in Windows and Windows Server (Note: Windows XP only supported SMB v1).Click here ==> http://gsurl.in/2XI3
- Audit installed software and keep it up to date: malware often uses flaws in outdated software. Keep all installed software up to date, not only on end nodes but also in the data centre. Patch Manager ==> http://gsurl.in/2XIa will also detect vulnerabilities in many third-party software, other than the operating system.
