The SSL Certificate and Your Website’s Security

The SSL Certificate and Your Website’s Security

 

When you are surfing the internet, a lot of information is being exchanged between the web host and the device being used to surf the internet. This type of information can always be easily breached by hackers, especially if it involves online transactions and this has always been a major issue when dealing with the internet. Nowadays, cases of online theft are becoming increasingly popular. There is one way of determining whether a site is safe to use through an SSL Certificate which is powered by the beauty of cryptography.

How SSL Cryptography Works?

Cryptography ensures that data is transmitted in a means that only the intended party can access it. You can easily determine a site which has an SSL certificate by the padlock icon that is displayed beside the web address. So how do SSL certificates work? SSL in full is Secure Sockets Layer. An SSL certificate provides tight security during the exchange of data.

PadLock Icon Showing SSL Security

In SSL cryptography, encryption makes use of separate keys for the decryption and encryption of data. Encryption keys are public and anyone can use them. But the decryption keys (ones used to turn encrypted data into meaningful information) are private and are kept secret. The SSL certificate, on the other hand, can simply be described as a tiny data file that has the appropriate information about a certain website. The information can be quickly read by the host connection once the request for connection is received. It is through an SSL that a website can prove its authenticity to a web browser.

How To Get SSL Certificate?

An SSL certificate is not handed out like a college certificate. There are a number of companies called Certificate Authorities (CA)that authenticate that a site/server is legitimate and sign a resultant digital certificate which is then stored, just like a cookie is stored on your browser. The certificate will continuously alert all incoming connections and protocols that the connection is trustworthy.

SSL Certificate Advantages

SSL certificates make online data-exchange, especially financial transactions, safer. It is a common rule of thumb not to trust any e-commerce site that does not have an SSL certificate. There is just too much information floating around online nowadays such as credit card info, banking information etc. The safety of all these vital information will be ensured by the SSL certificate, and every browser will accept the websites incoming connections. However, most small websites, such as blogs, don’t really need to supply an SSL certificate.

Steps to remove or detect keylogger from your computer

1. You should trace the behavior of you PC in order to find the common virus symptoms because the keylogger symptoms have much in common with the symptoms of other computer infections. We can refer slow computer performance, new icons on your desktop or in tray, network activity and unexpected pop-ups to these symptoms. Also you can notice that the text that you type can appear with little delay – this is the direct symptom that will help you in keystroke logger detection.
2. Open Task Manager in order to end the process of the installed keylogger. You should know that not every keylogger can be found in Task Manager. Many of them hide their traces. But you should still check the possibility to end its process:
   
   • Press CTRL+ALT+DELETE, then select Task Manager in the menu.
   • Select Processes tab, scroll the list. Find the process that is called winlogon.exe. One process with such a name is a normal thing, but if you have 2 processes with the same name, then you have a keylogger.
   • Highlight the second winlogon.exe and click End process (you should end only the second process with such a name)
   
   If there is just one process with such a name, then you should check all other processes, using the special services that contain information about most of the processes to detect the malicious one. You can use Liutilities, Neuber or any other service that you know. If you are an experienced user, then it will be much easier for you to check the processes, because you will not miss the system process with any malicious.
   If you end the process that belongs to keylogger, then the program is deactivated till the next reboot and the third party will not get your personal information.
3. You should also look through the list of the installed programs. So, click Start menu, then All programs, try to find there the program that you did not install. Uninstall such programs.
4. How to detect keylogger? You can also detect this malicious program with the help of Startup list. So, you should follow the instructions:
   
   • Press Windows+R buttons, then type msconfig in the line and press Enter
   • Select Startup tab and disable all the unknown programs
   • Then restart your computer.
   
   

There are all the manual instructions that will help you to find keylogger on your computer and deactivate it...

INTERNET SECURITY TIPS

 

Basic Security Tips

This basic Network Security Guide provides useful security tips and methods to secure your network such as installing a updated antivirus program, email scanning programs, network monitoring tools, internet access policy and other security prevention methods. Network security is a very important aspect of a computer network. Minor security vulnerability can result in a heavy loss of the critical data of your server and other client computers. Keeping the computer as well as network secure, is the big responsibility of the network administrator and the security specialists. There are lot of security measures and prevention methods which I will discuss in this section. Typically a computer network can be attacked by a number of ways such as virus attacks, unauthorized access, cryptography attacks and a number of other security threats.
A network security threat can be prevented if you have an updated antivirus program, regularly scan all the network devices, emails, open ports, server and client computers. It’s the responsibility of the network administrators to check and deploy the missing security patches in all the network computers. They should also remove the unnecessary network shares, users accounts, wireless access points and restrict the access too the network users. There should be proper training of the network users, network administrators and IT managers about the vulnerable things that cause a network to be attacked. A network administration of an organization should be highly skilled person and have much experience in network/system administration as well as dealing with the security issues.
Security Threats
There are a number of security threats that can be the cause of a network security attack. Main security threats are denial of service, distributed denial of service, viruses, Trojan horses, spywares, malwares, unauthorized access to the network resources and data, accidental deletion of the files and the uncontrolled internet access.
Virus Attack
A computer virus is a small program or an executable code that when executed and replicated, perform different unwanted and harmful functions for a computer and a network. Viruses can destroy your hard disks and processors, consume memory at a very large scale and destroy the overall performance of a computer or network. A Trojan is a malicious code that performs harmful actions but it cannot be replicated. Trojan can destroy systems’ critical data. A computer worm is a program that replicates to all network and destroy useful data. The viruses, malware, adware and Trojan horses can be prevented if you have an updated antivirus program with the latest pattern files.
Security policy
Being a network administrator, you should implement a security policy in your network and educate your network users and other employees about the security threats.
Email scanning
Email is a big source of a virus and malicious code. You should have installed an email scanning and monitoring program. You should also have a tight security policy at your proxy server and should block the unnecessary ports and web applications.
Unauthorized Access
Access to the network resources and data should be allowed only to the authorized persons. Every shared folder and resources in your network should have been accessed only by the authorized persons and should also be scanned and monitored regularly.
Accidental deletion of the files
What will you do if you accidentally delete your organization’s critical data? This is a question, which every network administrator and security specialists thinks of and wants answer. Few days before I read on internet news site that a computer technician accidentally deleted a financial company’s $ 10 billions records. To avoid the big troubles like this for you and for your company, you should have excellent data recovery software in your software inventory. Many data recovery tools are good enough to recover every piece of data if the hard disk is not physically badly damaged.
Network Monitoring Tools
You must have a good network monitoring tools to detect various suspicious things and monitor the various activities in your network such as network traffic, open ports, useless shared folders. GFI LanGuard Network security scanner is a good scanning and monitoring tool and it checks for all the possible methods, which a hacker can use to attack your network.
Internet Access Control
Internet can be a big source of viruses and the major security attacks, if you are unable to implement a tight security policy in your network, if you have a old definition anti virus program and if your haven’t put any check on your network user’s activity. Your gateway or proxy server, which is directly exposed to the internet should have very tight security, updated antivirus program and network monitoring tools.
Information Theft and cryptography attacks
Another threat to a network is to loss of the important information and this loss can be prevented, if you good encryption methods such as 128 bit security or 256 bit security encryption methods. In this way, your data when transferred through FTP programs, can be encrypted and can’t be read or use.
Unauthorized application installations
Another virus and security attack prevention method is to install only the authorized software applications to your network server and your all client computers. Nobody should be allowed to install any kind of program which can cause security threats such as songs or video programs, codec, gaming software or other web based applications.
Security Conclusion:
I tried to point out the major security threat prevention methods also provided the solutions to avoid them. There are a number of ways, which guarantee for the safety and security of your network.
I have summarized the all these method as below.
1. Perform regular network security testing.
2. Don’t provide more or unwanted access to any network user.
3. Must have an updated antivirus program.
4. Operating system should be regularly updated. If you have windows based operating system you can update it from the Microsoft website.
5. Keep inventory of your network resources such as devices and software applications.
6. Regularly scan TCP/IP services
7. Turn off your computer when you are away and don’t leave your computer unattended.
8. Put a strong network and system administrator password.
9. Implement a strong security policy.
10. Use a switched network, so that you can identify the problem very quickly.

What is a proxy server? When do we need one?

The word Proxy is derived from a Latin word proximus which means “close”.A proxy is actually a server which helps us maintaining our privacy on the Internet. It is just like a wall between you and the Internet. When you use a proxy, the webpage on the other side won’t be able to see you, webpage interacts with the proxy and proxy in return shows us the webpage. In this way a proxy server works. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server evaluates the request according to its filtering rules.

For example, it may filter traffic by IP address or protocol. If the request is validated by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client. A proxy server may optionally alter the client’s request or the server’s response, and sometimes it may serve the request without contacting the specified server.

A proxy server can be used for various purposes such as :
    Hiding machine or other servers from public. It provides security.
    To speed up access to resources (using caching). Web proxies are commonly used to cache web pages from a web server.
    To open blocked sites in college schools and some times in offices.
    To bypass security/ parental controls.
    To protect your real identity on internet.

A proxy server that passes requests and replies unmodified is usually called a gateway or sometimes tunneling proxy.A proxy server can be placed in the user’s local computer or at various points between the user and the destination servers on the Internet.

A reverse proxy is (usually) an Internet-facing proxy used as a front-end to control and protect access to a server on a private network, commonly also performing tasks such as load-balancing, authentication, decryption or caching.
