For Mr. Roberts1161
Off subject for Mr. Roberts posting name - I remember a television scene of the US Navy Choir on a stage singing and hosted by Henry Fonda.  When done, one by one, the sailors walked down the small bleacher and said " Good night Mr. Roberts" to Fonda as they passed him left and right.  He almost broke down.  Incredible to see.

Focusing on Endpoints: 5 Steps to Fight Cybercrime
Great basics provided with any decent endpoint vendor dashboard. Good example is McAfee EPO. I would add a couple of things keeping in mind - Obviously there is no such thing as a 100% secure endpoint and the other well-known fact is more security slows down creativity and production.

1. Once a compromise is alerted remove the device from the network then re-image. Re-image is the cheapest most accurate way to avoid residuals. Scanning and cleaning cannot always catch everything.

2. Have a policy written up with the step by step procedures including a log of the alerts with the actual compromise listed and actions taken. This will show any recurring symptoms or false positives.

3. It is advisable to limit the ability to install new external software at an endpoint without admin rights. Set up an easy policy to some type of ticketed request for temporary rights, thus an audit is created, and shadow IT is controlled.

4. DLP is usually part of a good vendor product which should assist with unauthorized USB or other devices.

5. DMARC EMAIL policies, procedures, benchmark/train/retest should help with phishing.

6. Proxy whitelist or blacklist to assist controlling things like rootkits.

Specifically Block/Control Internet Access
For some reason one area that is continuously overlooked or under-managed is Internet access from the company network.  For example, an organization I am familiar with only recently started locking their company laptops from use of USB devices.  However, from these same laptops users can access cloud drives, download and upload files without warnings or security hurdles.  In other words, whatever the intent of the USB block, all that energy was wasted by access being provided to the Internet for WAN and LAN users.

In contrast, a past company of mine that developed financial software blocked all Internet access by default, prevented USB access to all systems by use of physical system locks and protected all their Ethernet ports with similar locks.  Emails were filtered on a level of paranoia and no attachments were allowed incoming or outgoing.  A document control system that was only accessible on the LAN (no VPN access) was exclusively used for exchange of documents, and all the code bases were accessed from secured local servers serving up Git to onsite developers.

Obviously the comment here is going to be that many companies are hybrids with local offices and also remote offices and contractors.  Some companies don't even have physical offices.  This could point to why many organizations like the one who spent so much time securing USB port might overlook the existence of Google Drive and MEGA being just a URL away.  It also begs the question whether convenience and the modern expectation of immediate response might be one of our biggest Information Security setbacks...

The 10 Most Impactful Types of Vulnerabilities for Enterprises Today
Managing system vulnerabilities is one of the old est - and most frustrating - security challenges that enterprise defenders face. Every software application and hardware device ships with intrinsic flaws - flaws that, if critical enough, attackers can exploit from anywhere in the world. It's crucial that defenders take stock of what areas of the tech stack have the most emerging, and critical, vulnerabilities they must manage. It's not just zero day vulnerabilities. Consider that CISA's Known Exploited Vulnerabilities (KEV) catalog lists vulnerabilitlies in widely used applications that are "actively exploited," and most of them are flaws that were discovered several years ago and have been fixed. There are also emerging vulnerabilities in 5G networks, cloud infrastructure, Edge applications, and firmwares to consider.
