Gnome3 Customise Shell Theme

I recently re-installed Ubuntu 1804 on my laptop and I though I would give the PopOS desktop theme from system76 a try. The verdict? It's very very nice. Next time I do a re-install or get a new laptop I think I will use PopOS which is based in Ubuntu anyway. Side note: If a System76...

BrandPost: 5 Steps to Get Ready for 802.11ax

It’s a mobile, cloud and IoT world. Whether it’s a workplace, a classroom or a dorm room, people are using a variety of devices beyond the usual phone and laptop combo—smart TVs, gaming consoles and fitness trackers, for starters. Offices, stores and manufacturing floors are outfitted with sensors that keep us safe, regulate the temperature, water the plants and run the production line. People use a broad variety of applications such as voice and video from their mobile devices. And expectations are at an all-time high. People will simply ditch digital services that don’t work. No one wants jittery presentations and dropped calls. The network experience must be flawless.To read this article in full, please click here

IDG Contributor Network: Can TLS 1.3 and DNSSEC make your network blind?

Domain name system (DNS) over transport layer security (TLS) adds an extra layer of encryption, but in what way does it impact your IP network traffic? The additional layer of encryption indicates controlling what’s happening over the network is likely to become challenging.Most noticeably it will prevent ISPs and enterprises from monitoring the user’s site activity and will also have negative implications for both; the wide area network (WAN) optimization and SD-WAN vendors.During a recent call with Sorell Slaymaker, we rolled back in time and discussed how we got here, to a world that will soon be fully encrypted. We started with SSL1.0, which was the original version of HTTPS as opposed to the non-secure HTTP. As an aftermath of evolution, it had many security vulnerabilities. Consequently, we then evolved from SSL 1.1 to TLS 1.2. To read this article in full, please click here

Banking-Grade Credential Stuffing: The Futility of Partial Password Validation

Banking-Grade Credential Stuffing: The Futility of Partial Password Validation
Banking-Grade Credential Stuffing: The Futility of Partial Password Validation

Recently when logging into one of my credit card providers, I was greeted by a familiar screen. After entering in my username, the service asked me to supply 3 random characters from my password to validate ownership of my account.

Banking-Grade Credential Stuffing: The Futility of Partial Password Validation

It is increasingly common knowledge in the InfoSec community that this practice is the antithesis of, what we now understand to be, secure password management.

For starters; sites prompting you for Partial Password Validation cannot store your passwords securely using algorithms like BCrypt or Argon2. If the service provider is ever breached, such plain-text passwords can be used to login to other sites where the account holder uses the same password (known as a Credential Stuffing attack).

Increased difficulty using long, randomly-generated passwords from Password Managers, leads to users favouring their memory over securely generated unique passwords. Those using Password Managers must extract their password from their vault, paste it somewhere else and then calculate the correct characters to put in. With this increased complexity, it further incentivises users to (re-)use simple passwords they can remember and count off on their fingers (and likely repeatedly use on other sites).

This is not to distinct thinking that originally bought us complex Continue reading
