Information Security Learning Resources part 2

   Today we have part 2 of a 2-part guest post by security analyst Chris Goff.  Chris has collected a set
of info, links and lists that definitely qualify as extremely cool resources!  You can check out Chris' website at http://chris-goff.com/ or follow him at https://www.linkedin.com/in/goffchris

   There's a lot of info packed in here, and it's pretty technical. But you don't have to memorize it all now and there won't be a test!  Just skim it, enjoy it and bookmark it!

Security Concepts

There are three key concepts of information security which you may or may not be familiar with:

    -      Confidentiality

o   Confidentiality is the characteristic of information whereby only those with sufficient privileges and a demonstrated need may access certain information. When unauthorized individuals or systems can view information, confidentiality is breached.

    -      Integrity

o   Integrity is the quality or state of being whole, complete, and uncorrupted. The integrity of information is threatened when it is exposed to corruption, damaged, destruction, or other disruption of its authentic state. Corruption can occur while information is being entered, stored, or transmitted.

    -      Availability

o   Availability is the characteristic of information that enables user access to information in a usable format without interference or obstruction. A user in this definition may be either a person or another computer system. Availability does not imply that the information is accessible to any user; rather, it means availability to authorized users.

This is known as the “security triad”. It can be further expanded upon:

    -      Privacy

o   Information that is collected, used, and stored by an organization is intended only for the purposes stated by the data owner at the time it was collected. Privacy as a characteristic of information does not signify freedom from observation (the meaning usually associated with the word), but in this context, privacy means that information will be used only in ways known to the person providing it. Many organizations collect, swap, and sell personal information as a commodity. It is now possible to collect and combine information on individuals from separate sources, which has yielded detailed databases whose data might be used in ways not agreed to, or even communicated to, the original data owner. Many people have become aware of these practices and are looking to the government for protection of the privacy of their data.

    -      Identification

o   An information system possesses the characteristic of identification when it is able to recognize individual users. Identification is the first step in gaining access to secured material, and it services as the foundation for subsequent authentication and authorization. Identification and authentication are essential to establishing the level of access or authorization that an individual is granted. Identification is typically performed by means of a user name or other ID.

    -      Authentication

o   An information system possesses the identity that he or she claims. Examples include the use of cryptographic certificates to establish Secure Sockets Layer (SSL) connections or the use of cryptographic hardware devices--for example, hardware tokens provided by companies such as RSA's SecurID--to confirm a user's identity.

    -      Authorization

o   After the identity of a user is authenticated, a process called authorization assures that the user (whether a person or a computer) has been specifically and explicitly authorized by the proper authority to access, update, or delete the contents of an information asset. An example of authorization is the activation and use of access control lists and authorization groups in a networking environment. Another example is a database authorization scheme to verify that the user of an application is authorized for specific functions such as reading, writing, creating, and deleting.

    -      Accountability

o   Accountability of information exists when a control provides assurance that every activity undertaken can be attributed to a named person or automated process. For example, audit logs that track user activity on an information system provide accountability. (Management of Information Security by Michael E. Whitman and Herbert J. Mattord)

Information Security Learning Resources

or information security for the self-learner

by Chris Goff

This is the result of many years of notes. This is by no means an exhaustive list, nor the definitive path to information security.

If you come across a dead link, use the Internet Way Back Machine (https://www.archive.org).

Bookmark these Google Search cheat sheets, they will come in handy:

Official Google Cheat Sheet - http://www.google.com/help/cheatsheet.html

Core competencies

Here are three core competencies within information technology that will provide a solid foundation on which to start a security career:

• Systems Administration
• Network Administration
• Programming

It is also critical that you learn to deal with people and business. Take some public speaking classes (Toastmasters: https://www.toastmasters.org/), volunteer for presentations at local groups, and volunteer to deliver training for folks at your workplace. One of the greatest methods of learning is to teach.

The core competencies are not a requirement, however be aware that InfoSec is expected to be a Subject Matter Expert (SME) on most topics. If you wish to be successful diversity of knowledge is key.

XP End of an Era or... Deja Vu All Over Again!

   Unless you just came back from time traveling, you know that Microsoft is ending support for the XP
operating system on April 8.  To be clear... April 8 is Patch Tuesday, so that will be the last set of updates for XP.  Sort of.

   XP has been one of Microsoft's most popular desktop operating systems and many organizations are dependent upon it.  Many organizations have not yet updated to Windows 7 or 8 and the clock is ticking.  I'd like to look at what that means and share a few ideas of what we can do to protect ourselves and our organizations.

   Microsoft will be stopping all patches, hotfixes and enhancements to XP after April 8.  Anti-virus signatures will continue to be made available.  This means that any vulnerabilities that are discovered or disclosed might not be fixed.  Organizations will need to figure out if they are vulnerable to any new threats and then weigh the risks associated with their options.

   There has been some speculation that online criminal organizations may be stocking up on new vulnerabilities so these can be released after the last patch date.  We can't know if this is true, but it is possible.

   So... if you are still running XP, and need to continue to run XP, what can you do?  Let's do a high-level threat analysis:

No, You Can't Have Local Admin!

   If you have responsibility for security and/or access management for an organization, then there is a "simple" request that you have received, and will always receive... Users request local admin access to systems.

   Most of you know what I mean.  I'm referring to the local administrator or root account on a system.  When a person has local admin, they can access any part of the system, change or disable settings (including deactivating anti-malware or other security software), and, perhaps most importantly, install and run any software.  This last item is probably the primary reason people request this level of access.

   We're talking about Minimum Necessary... the idea that everyone should have exactly the level of access needed to do their job, and no more.  In most, if not all, organizations, far more people have local admin than really need it.

   Security vendor Avecto recently released a new study showing that over 90% of the most serious vulnerabilities in Microsoft software products in 2013 could have been mitigated by simply removing administrator rights.  Put another way, this means that only your systems administrators were vulnerable to all of the most critical Microsoft software vulnerabilities!  And these are the people who have the most access on your systems!  Here are a two good articles on the subject and here is a link to the full report.

   Let's break this down...
