NCSAM: Security in 140 characters or less…

Tom Liston, the Senior Security Consultant for InGuardians, Inc, has written a great blog on the SANS ISC diary, focusing on the basics of information security. His tips were sourced from Twitter; hence this story’s title, but they are a perfect fit for National Cyber Security Awareness Month.

Liston’s blog starts out by recounting a recent job. “I had just spent a week immersed in a corporate culture that seemed to have focused itself on so many higher-level security issues that the basics – the ‘Security 101’ stuff – was just plain overlooked,” he wrote.

“The more I thought about it, the more it bothered me.  It wasn't some fancy-schmancy 'leet h@x0r 0-day that let us take down this organization from the inside: it was stupid-simple low-hanging fruit… Think about it: Over the past year, how many high-profile hacks have been the result of awesome cutting edge skillz?  How many have happened because someone just flat-out did something dumb? We truly are neglecting the basics.”

Liston went to Twitter and asked other security professionals to share their wisdom. Some of the highlights are below, the rest can be seen on the SANS post, or on Twitter here.

If you can guess where PHPmyAdmin is installed, then so can attackers.

You are already pwn3d. The question is, "What will you do about it?"

Don't leave default passwords on the administrative interfaces of your 3rd party web applications.

Know your network - and all devices in it - well enough to spot unusual activity.

Security 101: If you don't need it, turn it off.

Computers remember a lot. Even more if you contact security personnel before you reboot.

If your product allows remote connections somebody WILL write a python/perl/ruby script to connect to it and send whatever THEY want.

A backup is not a backup until you do a restore.

Attack vectors and regulatory requirements change. "That's how we've always done it" is a poor and lazy excuse.

In your encryption system, your key is the weakest link. If it isn't, you're doing it wrong.

If you don't log "accepts" in your FW logs for admin protocols you will have no way of knowing when those accounts are abused.

Analyse your logs in detail, it is those with their heads buried in your logs that hold the key to prevent, detect and recover.

Give only the permissions required to do the normal daily duties, nothing more. Special logons for special occasions.

Unencrypted Wi-Fi is never secure. WEP = Unencrypted Wi-Fi. Trust me. Stop using it. Now. Really.

What Color is this Dress?

White and Gold or Blue and Black?
Well this one has been trending all over the web, just what color is this dress? It all started in Scotland when the mother of a bride-to-be sent a picture to her daughter asking what she thought of the dress. The bride and groom each saw the image differently, this then got posted online and picked up by some viral sites. The lighting in photo is probably  causing different people to see it as either white and gold or blue and black. Prof Stephen Westland, chair of color science and technology at a University in the UK told the BBC that it was impossible to see what other people see but that it was most […]

Octopus hunts on land, grabs crab (Video)

This crab is minding its own business searching the rock pools for food when suddenly an octopus leaps out of the water and grabs it. The amazing thing is that the octopus does not just jump on the crab it actually pulls it all the way back to the rock pool it came from.

Stunning Mars Rover Selfie

This image by the Curiosity Mars rover is not exactly your typical selfie. It is made up of a bunch of images taken by the rover during January 2015 by the Mars Hand Lens Imager. This (MAHLI) camera is at the end of the robot’s arm. For a sense of scale the rover’s wheels are about 20 inches diameter and 16 inches wide. Check the annotated image below for more information on the surroundings. Also if you really want to see some detail click this very large image, 36mb, at NASA.  

How the Sahara Helps Feed the Amazon (Video)

Sahara to Amazon
This cool video from NASA shows how dust is transferred across the Atlantic to the Amazon rainforest and helps nourish the plants growing there. For the first time scientists have measured the amount of dust and the amount of phosphorus in the dust. The later acts like a fertiliser and helps replenish the phosphorus the rainforest loses each year, around 22,000 tons. Amazing how something we perceive as being desolate like a desert actually has an important role in sustaining somewhere we see as teeming with life.
