The interception the data packets flowing between visitor and website is only one way internet criminals gain access to sensitive information. So even though the browser is indicating a secure connection, some of the interactions may not be secure or encrypted at all. There are also potential exploits that can endanger this data exchange.
Examples include:. All of these are well-known methods used by internet bad-actors to extract information being exchanged between websites and users.
But all of these can be effectively defended against using a relatively simple website security best practices. At IowaComputerGurus, we strongly agree that website security is one of the most important priorities of the day. We have created a special white paper to help website owners, administrators, and other developers understand website security best practices.
Main Menu. The Need for Common-Sense Website Security If everything we knew about hackers, ransomware, identity theft, and website security was limited to reports from the major media, no one would ever build a website again.
Website Security Protects Everyone Another problem is that many companies perceive website security as a form of self-protection. SSLv1 was never publicly released, so the first real experience we all got with SSL came in with SSLv2, which contained a number of serious security flaws. This is where SSL itself can be a direct vulnerability.
As technologies progress not all websites progress with them, and a lot of websites still support older protocols despite using a newer SSL certificate. Hackers can use this vulnerability and older support to perform a protocol downgrade attack - where they make the user browser reconnect to the website with an older protocol - and while a lot of modern browsers will prevent SSLv2 connections, SSLv3 is still more than 20 years old.
When you log in to a website the server sends back a cookie, this means you don't have to keep logging in and out of the site it remembers you.
The issue is then when you continue to browse the website on HTTP, the same authentication cookie is being sent and received over an unsecured connection, which could result in an attacker intercepting the cookie, stealing it, and then impersonating you at a later date.
For full coverage, a website should also be using HSTS to protect against protocol downgrade attacks and cookie hijacking. The technology also doesn't secure a website against thousands of other known hackable exploits, which can compromise user data. It is one piece in a cybersecurity jigsaw that is on the face of it one of the easiest security features to identify - especially from a web-crawler point of view.
Double check your domain and make sure everything is in place. SSL is enabled, but there is no certificate. What is it? Is it happening to me? Things you need to make sure are secure are: Images Cascading style sheets CSS Javascript You can check to see if these things are secure by checking how they're linked in your code.
How to fix If you find any links that are http , you need to make them secure. Tagged: Security. Encryption protects you from eavesdropping and transparent MITM attack altering the messages. But SSL does not only provide encryption, it also provides authentication. Server must have a certificate signed by a well known certification authority CA that proves its identity.
Without authentication, encryption is useless as MITM attack is still possible. The attacker could trick you into thinking that he is the server you want to connect to. Private chat with the devil is not what you want, you want to verify that the server you are connecting to really is the one you want to connect to. Authentication protects you from MITM. You seem to say that you secured the transfer using SSL.
This is not enough, the security of your server can be compromised — you should not store passwords there in plain text, use their hashed form, with salt added, …. SSL encrypts data both when sending and receiving. MITM attacks are possible virtually only when the attacker has certificate signed by an authority the client trusts. Unless the client is tricked into not using HTTPS, nobody can read nor modify the messages being sent. There are several other, too.
Method is just a property of HTTP request. All messages are secured, both requests and responses, regardless of HTTP method being used. SSL protects data in transit by encrypting it. It only ensures, to a client, that data will make it from their computer to your server without being intercepted or altered the encrypted data could be intercepted but has no meaning without decryption. That said, it is the client's responsibility to ensure that SSL is functioning properly before they send any data or trust output from the server.
There are attacks that will remove SSL from the connection, but not that will intercept or alter data sent over a secured SSL connection. SSL does not provide any security once the data is on the server.
It is still necessary to use hashing and server side encryption if you want to protect the data at rest from breaches to the server itself. SSL only secures the connection between client and server. In theory it does it fairly well ok, there are some problems - but these are minor compared to all the other problems : as long as none of the about CA you trust inside your browser gets compromised or works together with some agencies and gives them intermediate CA to do man-in-the-middle attacks.
And, like I said, it secures only the connection between client and server. Also, the server can be compromised etc. In summary, SSL is kind of necessary to secure data, but it is not the only thing you need to do to keep data secure.
