Network Scanning - So who still does this?

So, are the days of Network port scanners behind us? or do organizations still use these tools as part of a proactive/preventative service? I can certainly see when you could use a network port scanner to validate that a machine that is behaving suspiciously is listening on ports that is shouldn't, but wouldn't proper log monitoring, SIM/SIEM, and end point/HIDS systems catch that before it would ever be detected via a network based scan?

From a compliance perspective I can see the need to assess the configuration of key systems, but again there are probably better ways to do this (again using endpoint protection, integrity/configuration management tools, and compliance type tools) than what you can accomplish with a network based scanner.

Thoughts?

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...
