PGP sign your emails: PGP, or “Pretty Good Privacy” signed emails involve a cryptographically encrypted key function that ensures a given message was sent from the source it was sent from and was not altered at any point after being sent. It is important to secure e-mails in this manner since un-signed e-mails can be decrypted and used as template for false messages in the name of the digital sender. Moreover, private/public authentication keys prevent PGP signed from being read by unintended recipients.
OTR Instant Messaging: OTR, or “Off the Record” instant messaging is method by which a digital sender of an e-mail can maintain deniability should the e-mail be decrypted. OTR messages are un-signed and therefore can have been sent from any user without any need for authentication. In this way, OTR messages make a digital conversation as informal as a private conversation.
Encrypted VOIP: The main danger to unencrypted VoIP conversations is interception by just about anyone who has access to the particular network. The conversation can also be recorded and altered. Due to user demand, most VoIP networks include encryption features to protect from hackers. These features prevent both recording and alteration of VoIP conversations using recipient authentication keys.
TOR web browsing: TOR, or The Onion Router, web browsing allows users to anonymously access a network. Use of the network can protect a users’ access codes as well as digital identity from would-be hackers. While the TOR system is vulnerable to traffic analysis, by overlaying several Onion Routers, TOR web browsing provides considerably increased privacy. This form of web browsing was originally developed by the U.S. Navy.
Secure tunnels to safe havens: Data need to be stored in safe havens to guard against unexpected and crippling data loss. In addition, to get to these safe haven data storage facilities, the data need to take a secure tunnel route through the internet from the original storage location. In this way, the data is protected the entire way to the data backup storage location.
Dynamically encrypted hard disk: In order to protect the files and folders stored on individual hard disks from unauthorized use or duplication, the disk must undergo full disk encryption. This form of disk protection will prevent outside use of the contents of the disk, including swap space and temporary files and folders. In addition, since the entire disk is encrypted, the user does not have the option of which files to encrypt and the encryption protocols themselves are encrypted. If the protocols are destroyed, the hard disk contents are purged as well.
Staying updated: Package managers, such as Synaptic, manage multiple incoming packages and feature a package search utility. In addition, Synaptic and other package managers, use as their source multiple and mixed repositories such as ftp or http sites, as well as network and local file systems. With a bug patch, the package manager can keep a system updated against the latest bugs and glitches. Modern package management software is capable of system-wide comprehensive upgrades to correct system bugs all in one fell swoop or get up to date.
Protocol encryption for P2P: A huge portion of internet traffic is P2P, or peer to peer and the Internet Service Providers have only two options to deal with the enormous workload. They can increase their service capacity, the expensive option, or, they used specialized system so they can throttle individual users’ BitTorrent traffic, essentially slowing the user interface to a crawl and preventing the P2P connection. Protocol Encryption works to cloak the P2P traffic and reduce the risk of the Service Provider throttling the BitTorrent traffic.
Have a serious password: Hacker attacks of passwords are surprisingly fast-acting. For instance, a four digit password can be cracked almost instantly by even the simplest class of password attack. A good, serious password includes numbers, common symbols, and letter, both upper and lower case. This way, a hacker must go through the maximum number of permutations to crack the password. If all the aforementioned elements are involved in a password, it can take until the end of time for a even a very advanced and sophisticated password attack to succeed.
Use Linux: Linux is an open source code based operating system and is an alternative to Microsoft’s Windows. It differs from Windows in that the source code is open and therefore constantly updated and improved with the users interests in mind and without any central control or profit driven motivations. Linux Security Modules, or LSMs, allow Linux systems to use multiple security modules and implement a mandatory access control module. This results in hooks or up calls when any sensitive system is accessed controls access on a user level.
