Tips & Tricks: Lock Your Computer

Prevent unwanted access to your computer by locking it when you get up. 

Windows + L will lock your system right away, requiring a password (if you’ve set one) to log in again.

On macOS use Cmd + Option + Power to log off. On the latest revision of macOS (High Sierra) a quicker option to simply lock the screen was added which works using the shortcut Cmd + Ctrl + Q.

National Cybersecurity Awareness Month Week 5: Protecting Critical Infrastructure from Cyber Threats

The theme this week is: The essential systems that support our daily lives – such as electricity, financial institutions, and transportation – are all dependent upon the Internet. Building resilience in critical infrastructure is crucial to our national security. Week 5 will look at cybersecurity in relation to keeping our traffic lights, running water, phone lines, and other critical infrastructure secure.

The Internet has become a vital part in our lives, including the operation of pretty much everything. I went to the dentists after Hurricane Irma and the dentist could not even take x-rays for patients because the x-ray machine has to be connected to the Internet. That is a minor item, but think of all the medical equipment that needs power and or Internet. This is a huge vulnerability.

Most of the time we are concerned about our smartphone connectivity to the Internet and protecting our personal information, but the most important aspect is the availability of utilities (power, water, etc.) for everyone. Here is a brief article discussing the electrical grid: “cybersecurity experts offered solutions to protect the U.S. electric grid, including moving the grid off of the public Internet, and using quantum encryption capabilities.”

Tech Terms: Malvertising

Malvertising is a deceptive process of injecting and spreading malware through otherwise legitimate online advertising networks that display ads on reputable web sites and pages.

A portmanteau of “malicious advertising,” malvertising has become more problematic in recent years, as newer forms of malvertising can infect computers and mobile devices without any action taken on part of the user – in other words, without the user even needing to click on the malware-laden ad.

The Payload and High Costs Associated with Malvertising
Malvertising code can secretly run on your computer, deliver malware payloads, and execute the payload before you or your security software has a chance to identify and prevent it from happening. And malvertising creators have started scanning their products before releasing them into the wild to make sure that they aren’t readily picked up by antivirus software.

The payload of malvertising can range from loading ransomware onto a computer to injecting keystroke-monitoring spyware to any range of activities that interfere with or disrupt the proper functioning of a computer, mobile device or network.

A joint report published in late 2015 by the Interactive Advertising Bureau (IAB) and Ernst & Young has estimated the digital industry loses approximately $1.1 billion a year to malvertising.
