Slashdot asks if password masking — replacing password characters with asterisks as you type them — is on the way out. I don’t know if that’s true, but I would be happy to see it go. Shoulder surfing, the threat is defends against, is largely nonexistent. And it is becoming harder to type in passwords on small screens and annoying… Continue reading Password Masking
I am in close proximity to the moment, where I will need to migrate from my old ssd and data hdd to new ones (wear and age), so I’m rethinking my environment. Please, give me suggestions about what should be improved regardin… Continue reading How to properly store, encrypt and backup passwords for home and office use

I have a homework question that suggests that applying security and usability best practices isn’t enough to create a secure and usable system. What am I missing? Why isn’t this enough?
If I follow usability best practices w… Continue reading Why isn’t applying security and usability best practices enough?
Back in March, Rolf Weber wrote about a potential vulnerability in the WhatsApp protocol that would allow Facebook to defeat perfect forward secrecy by forcibly change users’ keys, allowing it — or more likely, the government — to eavesdrop on encrypted messages. It seems that this vulnerability is real: WhatsApp has the ability to force the generation of new encryption… Continue reading WhatsApp Security Vulnerability
A few days ago, I blogged an excellent essay by Filippo Valsorda on why he’s giving up on PGP. Neal Walkfield wrote a good rebuttal. I am on Valsorda’s side. I don’t like PGP, and I use it as little as possible. If I want to communicate securely with someone, I use Signal…. Continue reading The Pro-PGP Position
Filippo Valsorda wrote an exellent essay on why he’s giving up on PGP. I have long believed PGP to be more trouble than it is worth. It’s hard to use correctly, and easy to get wrong. More generally, e-mail is inherently difficult to secure because of all the different things we ask of it and use it for. Valsorda has… Continue reading Giving Up on PGP
Every few years, a researcher replicates a security study by littering USB sticks around an organization’s grounds and waiting to see how many people pick them up and plug them in, causing the autorun function to install innocuous malware on their computers. These studies are great for making security professionals feel superior. The researchers get to demonstrate their security expertise… Continue reading Security Design: Stop Trying to Fix the User
In my network, I have the clients directly connected to the server; but in the new PCI policies, they required to use jump servers.
What is the advantage of using jump servers for security reasons?
How can I use two-factor … Continue reading Jump Servers for security
CONIKS is an new easy-to-use transparent key-management system: CONIKS is a key management system for end users capable of integration in end-to-end secure communication services. The main idea is that users should not have to worry about managing encryption keys when they want to communicate securely, but they also should not have to trust their secure communication service providers to… Continue reading CONIKS
