Enterprises have been battling security breaches for decades, but now the intrusions are multiplying at tremendous rates, putting enterprise digital information at great risk. Opportunist attackers seek to exploit vulnerabilities in enterprise security policies and systems to achieve their malevolent goals.

Experts believe most breaches can be prevented if enterprises make information security a high priority by installing and implementing powerful security tools. They must take protective measures to keep information from being stolen or damaged, including detecting when information has been damaged, identifying the cause of the damage, and recovering the lost or damaged information. Fortunately, there are a number of robust tools available to protect enterprises from substantial breaches.

Every IT environment needs a strong security strategy. That strategy can include tools for specific applications or situations, but fortunately they don't have to cost a lot. The easily available and free tools discussed on the following pages can help diagnose and monitor threats, prevent intrusions, secure passwords, ensure security compliance, and much more. Additionally, when enterprise cloud computing and BYOD policies open the door to security threats, these tools protect against breaches and exploitation, allowing businesses to reap the full advantages of cloud computing without risking the security of the enterprise.

There's no need for your business to be at risk. Check out the free security tools described here -- in domains spanning cloud, network, data, wireless LAN, identity and access management, and endpoint security -- to strengthen and supplement your enterprise security.

"Indeed, you get what you pay for.  I don't trust any free antivirus/security software; they tend to be malware in disguise -- especially the ones that are particularly alarmist about how much danger your system is in."

Joe, I don't know it's a reality or myth; most of the people have a mentality that open and free security tools can be a malware too. I had a bad experience in past, with a free security too and such loops are identified by kasperskey.  It can also be a business trick, which forces me away from free tools and to continue with kasperskey.

"Right Mynet, you'd think companies would protect valuable data, but that didn't seem to be the case with Target and many of others where criminals didn't really have that hard of a time breaching their systems"

Marcia, you may be right. I think again it depends up on the value of data. If companies found that it's precious then obliviously they will protect it and junk datas which are of No value can be unprotected. All types of protection have a cost tag too; so they will only protect dats which are worthy.

Re: free security tools

@Marcia   I really like AVG as a antivirus protection, I have shuffled between Avast and AVG, and now I am back to AVG because Avast doesn't seem to be proactive enough.  

I think that was the issue with AVG a couple of versions ago but this latest incarnation is their best effort by far. I highly recommend it - Avast has some work to do and they will eventually.

The Swiss Knife of Network Security

This is a great resource, so much here I am going to have to come back to this to really let all of the possibilities sink in.

I think I will start with the Network Security Toolkit which looks to be the Swiss Knife of Network Security !

Thanks to whoever put this together - always learning something new at Network Computing !    

Time well spent !

Re: free security tools
At some point, organizations learn the lesson the hard way that cost-saving line items are just as important as revenue-generating line items.

" I've also had a bad experience with some free antivirus I tried out for my personal PC. It behaved like adware. It seems those problems can crop up with consumer-type free security tools. Have you seen the same problems with free security tools that can be used in an enterprise?"

Marcia, enterprise peoples won't take such risks. I never seen in my office, they are using any free/open source security tools.  Once we have used the free security tool from MS, but not worthy and replaced it with kasperskey immediately.

Re: free security tools
"I agree Mynet, the C-level is paying much more attention to security these days in light of all the high-profile breaches. That didn't used to be the case; enterprises often were reluctant to spend a lot of money on security since it's not a revenue-generating part of the business."

Marcia, that may be true with certain cases. It again depends upon the value of data and info you holds. If its valuable; obliviously they will safeguard it.

I understand Ashish, I've also had a bad experience with some free antivirus I tried out for my personal PC. It behaved like adware. It seems those problems can crop up with consumer-type free security tools. Have you seen the same problems with free security tools that can be used in an enterprise?
