Everyone talks about computer security i.e being secure online but how many of us actually practice the effective security tips? Then when hackers or viruses attack, we look around to attach blame. Well, prevention is better than cure, so it pays in the long run to secure your system in advance.
Set up user accounts
One computer, many users, is a security disaster waiting to happen. Your files and data are your personal, private content and should be protected accordingly. To prevent other users from seeing or accessing your data, set up user accounts on your PC.
A user account shows an individual's specific data and not what is present on the entire system. It also specifies privileges on shared data, such as deleting/editing operations and what software can be installed on the machine.
This feature is especially useful when kids and adults use the same machine. With a separate user account, a kid can only view certain files and cannot modify or delete your important documents. Even if you are the sole user of the PC, set up a guest account, in case someone else needs to use the computer.
Secure your wireless network
With wired Internet access, there's little risk of someone encroaching on your network. But wireless networks do have holes in their security, so as the owner of the network, you need to be vigilant.
Setting up password-protected network access is the first step. You need to assign a network name and password to your Wi-Fi network. Use the latest wireless encryption methods like WPA or WPA2. Do not reveal your network password to others.
Installing security programs like an anti-virus, keeps your computer round-the-clock safe against viruses, malware, Trojan worms etc. and other malicious programs. For better protection, try to install complete security suites, that provide Internet security and firewalls along with anti-virus software.
Another bad trait of viruses is that they keep trying to find new ways to enter an unsuspecting computer. The only way to counter such attacks is to update your security programs on a regular basis.
You should also scan your computer regularly for dangerous programs. Schedule periodic scans, once-a-month scans, scanning new added devices and automatic full system scans, to ensure your PC is threat-free.
Social networking sites in particular, are fun online places to socialize but they are also preying grounds for the depraved. Parental control software allows you to set filters and block sites as well as receive warnings when suspicious activity is taking place online.
You can find this feature in the Tools option of most browsers. With search engines like Google, you can fiddle with search preferences settings.
Once you download and install or use a file, there's no telling what it will do to your machine. So be extra careful when it comes to downloading. Download files from trusted and preferably certified sites. Sites offering free, cracked versions of software programs are especially dangerous, as some cracks can contain malware.
When a download begins, you are asked to save the file before the downloading actually starts. Read the file name and its extension carefully, to ensure what you want is being downloaded. While installing a program, read the license agreement and make sure, only the program you want is being installed.
Sometimes spyware and hidden programs are bundled into the installer program, and are installed secretly along with your software. Scan your PC for threats after downloading files from the Internet.
You can keep your inbox sorted and clutter-free by using spam blockers and filters. Threat-wise, try to avoid opening emails from senders or addresses you don't know. A key sign of a malicious email is poor language. Weird, nonsensical text or poor grammar or even bogus-seeming email addresses are some signs of a harmful email.
Be especially wary of email attachments. Check the file extension. Files with .exe, .pif, .com,.bin or .bat extensions, can be malicious. If you do not know the sender of the email, do not open or download such files, just delete the mail. Instead of opening the attachment from the mail itself, save the file, let it download and scan it, before opening it.
So in case a virus has attacked your files or data is accidentally deleted, your data is never really lost, if you have a backup of it. Backup your data regularly, either by storing it on physical devices like CDs or by backing it up on a network.
Set a system restore point for your PC, so in the event of a system crash, you can restore your PC to a particular working state with your data intact.
With numerous passwords, it's understandable that remembering them all is difficult. So you can write them down but the place where you store this info, should be secure. And once in a while, please change your passwords.
If in case, they are revealed, updating the passwords can render all hacking attempts as naught. Another safety precaution is the "remember me" option in most secure sites. If multiple users access the same PC, do not select this option.
The given computer security tips are just the tip of the iceberg, when it comes to securing your PC. For every good advancement in technology, cyber evil seems to get even more evil, so it pays to be vigilant in today's cyberspace.
