Antivirus software can help but it’s not invincible Image Credit: Gabriel Salvadó. Almost every person with the CIO job currently has some form of antivirus software deployed within their company. The thinking behind this software is that if the bad guys attach some malicious software to a document, image, or spreadsheet that comes into the company, then before anyone can open it up the antivirus software will catch it and the file will be quarantined.

Why I Love The Oracle Cloud Strategy

Chuck's Blog - EMC

It's usually infrastructure only, it's still purchased and operated as plumbing, and there are few compatible public cloud offerings. Second, there is a full line of on-prem systems engineered for database, applications and analytics. They do things other systems can't do. And, finally, Oracle has figured out how to bring subsets of the public Oracle Cloud into the data center, behind your firewall. Same functionality, same operational model, same pricing model, etc.

Keep Systems Updated. A common way for malware to attack is for it to find exploits and vulnerabilities in a system. Shield weaknesses by removing applications you no longer use, update software, browsers, operating system and plugins. Anti-virus programs can catch most malicious bugs that enter your system. Enable a firewall and a comprehensive malware removal program like Malwarebytes to detect and keep all types of malware away.

The use of VMware NSX for microsegmentation is a really popular use case, and so the topic of scripting distributed firewall (DFW) rules often comes up. I predicted a couple of years ago that Intel SGX (Software Guard Extensions) was going to be HUGE (see here ).
