Passwords aren't the problem or the solution

So there has been an article going around the IT/Security community a bit today that was an eye opener to many - and old news to most of us.

http://www.boston.com/bostonglobe/ideas/articles/2010/04/11/please_do_not_change_your_password/

This article starts with the catchy title "Please do not change your password" and alludes that it is better for users NOT to change passwords than to change passwords. I don't disagree that passwords are often more trouble than they are worth, and they can themselves become a weakness. This is not news folks, if you ask any certified InfoSec professional, they should advise you that multi-factor authentication is the right choice if you are serious about protecting access. One of the challenges has been to date that implementing this level of control is expensive and not usually done for leisure activities/web sites.

Any organization that is still relying on simple passwords as a security control in 2010 deserves the hacking that they no doubt have received. If you are in a regulated industry (i.e. health care, financial institution, or PCI compliance) or have intellectual property or trade secrets that you want to protect, passwords should not be a control that you look to as secure or appropriate to your environments.

Information Security is not for the faint of heart or for the lazy. You have to have professionals that stay informed about the threats that are manifesting, a rigorous maintenance process for your environments (including reliable methods for updating all systems with patches, monitoring your system for suspect activity, and responding in a reasonable way to any intrusions). You also must have environmental knowledge of where the key or sensitive data resides, the controls and monitoring in place to protect or alert you, etc.

One of the items that the author brings up is the complexity of security measures. This is unfortunately due to the complexity of the environments that we as Information Security professional are often tasked with protecting. The systems that most companies have deployed over the past 15 years or so have for the most part been developed and deployed without taking risk and security into account.

A couple easy suggestions for making any company more secure:

Some of these may not be appropriate for every environment, and some should be part of a larger security program or control framework (if you need more guidance here check out ISF, ISO27001, or NIST-800).

1) Do not let users have administrative access to their systems by default. There are a number of ways in any OS to prevent the users from having too much access (sudo, runas, etc.) there is no reason for most users to have admin access to a system. Many attacks will just fail if the user is not logged in as a local admin.

2) If you have something worth protecting, spend the time to assess the software, systems, networks, and other contributing factors to the systems that hold the "crown jewels". Propose more strict controls, monitoring, and assessment for these systems, and when something doesn't look right make sure to get to the bottom of it and find out what happened.

3) Inform your users, executives, and IT staff of what to do in the event of a security incident. Make sure they know who to call, what to expect when they call, and what kind of communication to expect if there is a serious outage. Likely this can be rolled into an existing data center plan or BCP/DR plan.

As I have often told executives when asked, "Security is a journey, not a destination" it requires the company leadership to be on-board to hire the right people, to establish policies and processes that are meaningful and appropriate to the level of risk, deploy technology to assist in maintaining the security controls and validating that they remain effective, and to enforce the policies and help to develop a secure environment.

Requirements for Information Security

If you want to get into Information Security you HAVE to be a/have this skill... Why this is total BS. Almost daily I see someone posting on twitter, trying to be helpful to folks who are looking to get into InfoSec. Often I see "If you want to be in Information Security (Cyber Security) then you HAVE to be a programmer" or "If you want to be successful you have to be a hacker/have a criminal record/have abused systems without permission" etc. While having technical capabilities (such as programming) and having the ability to compromise a system shows a specific skillset neither are required. When talking to people who are interested in Information Security I often refer to it as a cake, there are tons of slices, many flavors, many pieces and parts you can sample, choose to focus on, will be expected to know something about, etc. Incident Response and Forensics (my current focus) is not the only part of Information Security, and certainly not the only part tha...

Privacy considerations for home users

In light of the recent new stories regarding the recently signed legislation allowing ISP's to be able to sell your data http://www.vox.com/new-money/2017/3/29/15107110/republican-isp-data-privacy Here are a couple ideas and tips about privacy in general. Don't panic - a lot of the info was already being gathered, this isn't that large of a change regarding scope, it's more of a change to who can profit or sell it (which is a shift for sure). Remember a lot of the services you use today already gather your browser, activity, and search info (google, bing, yahoo, facebook, etc.). ISP's haven't implemented this yet, expect to see new terms of service in an upcoming bill, or an email sent to you, etc. If you would like to take some steps to try to preserve your privacy, here are some ideas and examples: VPN (Virtual Private Network) - this in essence creates an encrypted tunnel between two points on the Internet. One point being your system...

Busting the myth of the malicious insider

The Myth of the Insider Threat Too often after the announcement of a new breach, the first reaction from the victim company and the media is "another malicious insider attack".  Case in point, I was catching up on news from various sources and came across the following: http://www.idgconnect.com/abstract/19647/lessons-sage-leak " “We believe there has been some unauthorised access using an internal login to the data of a small number of our UK customers so we are working closely with the authorities to investigate the situation,” the Newcastle, England-headquartered firm said in a statement." Of course an internal login was used to access the data, as part of the attack lifecycle, during your reconnaissance phase you identify accounts to target for possible compromise, based on the access/role of the individual.   Phishing attacks or other simply attacks are often successful in gathering login credentials for individual users, which can then of...
