Blog Post Shout Out: Creating Passwords and Internet Privacy

This blog post shout out will focus on both security and privacy related issues.

While there has recently been a renewed focus to phase out passwords, until that happens we need to continue to manage them.

The following article discusses (among other topics) managing passwords. It focuses on providing security while making it easier for users to remember them. It also raises doubts about the need for changing passwords so often and provides evidence to back this up.

All of this advice may useful if you are trying to create or update your corporate password policy to make it more user friendly while still maintaining security.

How to hack the hackers: The human side of cybercrime by M. Mitchell Waldrop (Nature Journal)

================================
In an effort to preserve your privacy you may be using a VPN (defined) connection when browsing the internet using your computer or mobile devices.

However as noted by F-Secure in this FAQ article, this may not be enough to fully protect your identity since some information (namely your real IP address) can still be leaked via WebRTC traffic. Within that FAQ article they provide advice on how to prevent this leak for the most common web browsers.
================================
Related to the above topic of VPNs, using public Wi-Fi hotspots isn’t a good idea if you want to preserve your privacy as this Kaspersky article demonstrates.

While a VPN can assist with preserving that privacy when using a public Wi-Fi, it isn’t a perfect solution. For example, apps installed on mobile devices can still leak data as discussed in this article.

However, it possible to better control such data leakage on Android and Apple iPhones. A guide to do this for Android is available here.

For an iPhone, you can open Setting -> Mobile data and change the settings according to your preference. However, when you connect to a public Wi-Fi hotspot all the network connections in use by the apps will begin new connections or resume existing connections.

To minimise the amount of data leaked you should use a VPN (as I have already discussed above) for your mobile device. In addition, you should use the Low Power Mode option of your iPhone from Settings -> Battery and change the setting. This setting change will halt background tasks, delete Wi-Fi access point associations, previous new emails being received and automatic downloads. More information on this setting is available from here.

Next, turn on your VPN (Settings -> General -> VPN). A list of popular VPN providers is available here.

Using the above steps will help to minimise the amount of data leaked if you are privacy conscious and use an Android powered device or an iPhone. Full disclosure: as you know I use an Android phone so I haven’t intentionally provided more information/discussion on the iPhone.

I hope that you find the above references useful in maintaining your security and privacy. Many thanks to a colleague (you know who you are) for contributing the advice on using VPNs with mobile devices.

Thank you.
