Encrypt Microsoft Office Documents
If you are a Windows user, you often use the Office Suite to write documents, prepare presentations or do some financial calculations. Sensitive documents can be given a degree of protection using Office built-in encryption. Microsoft offers several features to help restrict access to documents through the use of passwords or encryption.
If encryption is enabled, the document is scrambled with an encryption code, making the contents of it unreadable to anyone who does not have the password required to decrypt the document. There are several encryption algorithms available for use with Word, Excel, and PowerPoint files.
Firefox: 10 Tips to Bolster Your Privacy
Web browsers are leaky faucets that are revealing email address, web sites you’ve entered, search queries and other information. This absolute invasion of your privacy is actually pretty common and there are several different ways you can take control and increase your privacy.
In this hack, we’re going to highlight 10 tips to bolster your privacy when surfing the Internet with Firefox. You can use any of these tips to add an extra layer of privacy to your browsing at work, on public computers or just on a shared computer at home.
Mount Remote File Systems Over SSH with SSHFS
If you work on remotely connected machines, most likely you’re going to use SSH to secure your connections. But, what if you just want to work with files on a remote server, but find SSH file transfer tedious in repetition and establishing a VPN tunnel is too complicated?
What you’re looking for is a simple tool for mounting remote file systems easily, transparently and securely as if they were just another part of your local machine. In this hack, we’ll show you how to configure Fuse and SSHFS to access remote file systems securely over SSH.
Clear the Page File to Prevent Data Leaks
Virtual memory is a truly great mechanism. It protects programs from one another and lets them utilize more memory than actually available. In a nutshell, you can think of virtual memory as an alternate set of memory addresses.
As you run more and more programs, at some point, you’ll begin running out of physical memory. Since things can get slower when this happens, the virtual memory manager will copy as much data and possible into main memory and leave the rest on the disk (the page file). This process is known as swapping.

Secure Browsing With Squid and SSH
Public areas that offer access to the Internet (airports, open wireless networks, etc.) have no security in place. If you’re at a public WiFi spot, your personal information can be sniffed by other malicious users. This hack will show you a way to secure your web browser when using public networks.
In a nutshell, we’re going to setup a proxy server (Squid) on a trusted SSH server and create a secure connection from our laptop, over a public network to a secure remote server. We’ll tell the browser to use the secure SSH tunnel as an HTTP proxy.
