Common Network Security Mistakes

Have you ever been scammed or had a computer virus take over your system. You're left wondering: “how the heck did this happen to me”? You thought you had followed all the standard advice on securing your network and computer, but you still ended up with a security breach or malware infestation.

Here Are 5 Common Network Security Mistakes You Might Be Making:

1. You're Not Using Strong Encryption On Your Wireless Network
Are you scratching your head because hackers broke into your network, even though you had wireless encryption enabled? You may have been using encryption, but you might have been using the outdated and highly vulnerable Wired Equivalent Privacy (WEP) encryption. WEP was cracked years ago and hacking a WEP-encrypted network is now trivial, due to a proliferation of easy to use WEP hacking tools. Even a novice hacker can break into a WEP-based network.
The Solution: replace your network's WEP encryption with Wi-Fi Protected Access 2 (WPA2). WPA2 is a much more robust wireless protection method and is the current standard for “secure” wireless networks. Some older routers may be too old to support an upgrade to WPA2 while others can be upgraded via a firmware update. Check your router manufacturer’s support page for your specific router to see if it supports WPA2.

2. Your Passwords Aren’t Strong Enough

A weak password can be a hackers gateway into your network, your system, and your online
accounts. Increased computing power has decreased the amount of time it takes for password cracking tools to crack a password.

You need to make your passwords as long, complex, and random as possible. Avoid use of dictionary words in your password as cracking tools test for these. Having one embedded in your password will help the tool find your password much quicker than if it had random characters in it.

3. Your System Doesn’t Have The Latest Security Patches

Hackers love to find systems with unpatched vulnerabilities because they can be exploited with specially crafted attacks that take advantage of the unpatched weakness. OS vendors are constantly detecting new threats in the wild and developing security patches to close the holes.

Most OSes feature a set-and-forget “auto update” capability that will automatically download and apply the latest security patches on a regular basis.

The Solution: turn on auto update for your OS security patches as well as any apps that have auto update capability. You should also periodically run a manual patch check to ensure that the auto update process isn’t broken.

4. You Don’t Have a Backup Strategy

When things go bad, your first question might be “do I have a backup of those files”? You shouldn’t have to ask yourself this question, you should know the answer, and the answer should be "let me go pull up my backup of those files”.

Backups are critical resources. Some computer malware such as ransomware can encrypt your files and hold them hostage. If you have a backup of your files then you can laugh at the ransom demand and tell those hackers to go stick it in their ear or some other orifice.

5. You’re Not Aware of The Latest Threats And Scams

Scammers and hackers are constantly evolving their tools and tactics. Educating yourself on the current threats is key to not falling victim to the newest and most dangerous scams and hacks happening in the world.

Anti Spam Server Software

The anti-spam tools correspond to different classes of products depending on whether they are installed on the server or on the PC. The anti-spam server software is considered more efficient and superior in terms of quality, yet it can only be achieved with a serious investment, more costly monthly fees to pay. Anti-spam server software is generally used by large companies or corporations that want to prevent unwanted mail messages from reaching their employees. There is 99% protection and detection of spam with the most technically advanced programs. Another issue of main concern for business is that it should not prevent the passage of legitimate mail messages.

When the anti-spam server software scans messages it actually organizes the emails into legitimate and spam folders by using special techniques and filters. Once the identification is over, the end user receives the legitimate mail while the rest of the messages are discarded. Just imagine what it would be like for someone who works on the computer, to clean hundreds of mails and select legitimate message from the multitude. This would slow down the business development by wasting at least one or two work hours per day. With an anti-spam server software, you are safe from such inconveniences.

The anti-spam server software meets corporate needs because of the possibility to be used throughout a network. The network administrator is usually in charge of the accuracy of the program, constantly checking for ways of improving the operation level. During a first stage of implementation, users may be required to check the mails on the server and flag the potential spam messages. It is also important to signal out any false positives, meaning, legitimate mail messages that are detected as spam by the tool. Notifying the network administrator about this inconvenience will allow for a finer tuning of the program and a better performance of the anti-spam server software.

Program combinations for superior computer defenses are also possible. Anti-Trojan and anti-virus protection can be incorporated in the anti-spam server software so that the spam emails with a high risk of infection may be isolated. This out-of-the box function has great applications for personal users too, not just for companies alone. The setting that allows one to check the emails on the server and detect the potential spam without getting it into contact with the PC operating platform is crucial for minimizing virus infection risks. The features of most anti-spam server software tools include various management functions that enable Internet reports, server-based auto replies and mail monitoring.
