What is the acronym for Security Assertion Markup Language?
The Organization for the Advancement of Structured Information Standards (OASIS) is working on the Security Assertion Markup Language (SAML).
Is there consensus on a strong authentication scheme?
The following options can be considered but there is no clear consensus on a strong authentication scheme.
What is website security?
Website security is the last thing that many companies will think while they're on their website building process. Even if a website security expert is hired in their team, they'll always focus how and when to put their websites live – leaving major vulnerabilities unattended.
What does it mean when a website is not authorized?
An authorization failure can also disrupt your website. It means that when a function is called on the server, proper authorization was not performed. A lot of times, website developers rely on the fact that the server side generated the UI. They think that the functionality that is not supplied by the server cannot be accessed by the client. It is not as easy as they thought, as a hacker can always fake requests to the “hidden” functionality and will not be prevented by the fact that the UI doesn’t make this functionality easily accessible. Nothing can stop an attacker from discovering this functionality and abusing it if authorization is missing.
What is form injection vulnerability?
This is another form injection vulnerability that can input sanitization failure. A hacker sets up your web application JavaScript tags on input. When this input is returned to the user unsanitized, the user’s browser will carry it out. It can be as simple as crafting a link and persuading a user to click it, or it can be something much more sinister. On page load the script runs and, for example, can be used to post your cookies to the hacker.
Do website security personnel always make sure to personalize your security settings such as passwords and authentication?
Any responsible website security personnel will always make sure to personalize your security settings such as passwords and authentications. Perhaps, some people are still human to miss important things in their jobs. Some concrete scenarios are: They let the application run with debug enabled in production.
Is website security proactive or defensive?
You have to understand that an effective approach to website security must be proactive and defensive. This is a gentle reminder to you that website security must be taken seriously. It's good to be worried about the bad effects of it to your business and reputation.
Should passwords be hashed?
Information (such as credit card details) and user passwords should never travel or be stored unencrypted, and passwords should always be hashed. And while it goes without saying that session IDs and sensitive data should not be traveling in the URLs.
What is web security vulnerability?
This web security vulnerability is about crypto and resource protection. Sensitive data should be encrypted at all times, including in transit and at rest. No exceptions. Credit card information and user passwords should never travel or be stored unencrypted, and passwords should always be hashed. Obviously the crypto/hashing algorithm must not be a weak one – when in doubt, web security standards recommend AES (256 bits and up) and RSA (2048 bits and up).
When does web security become a priority?
For all too many companies, it’s not until after a security breach has occurred that web security best practices become a priority. During my years working as an IT Security professional, I have seen time and time again how obscure the world of web development security issues can be to so many of my fellow programmers.
What is a SQL injection flaw?
Injection flaws result from a classic failure to filter untrusted input. It can happen when you pass unfiltered data to the SQL server (SQL injection), to the browser (XSS – we’ll talk about this later ), to the LDAP server (LDAP injection), or anywhere else. The problem here is that the attacker can inject commands to these entities, resulting in loss of data and hijacking clients’ browsers.
How to store sensitive data?
If you don’t need sensitive data, shred it. Data you don’t have can’t be stolen. Do not store credit card information ever, as you probably don’t want to have to deal with being PCI compliant. Sign up with a payment processor such as Stripe or Braintree. Second, if you have sensitive data that you actually do need, store it encrypted and make sure all passwords are hashed. For hashing, use of bcrypt is recommended. If you don’t use bcrypt, educate yourself on salting and rainbow tables.
What is an attacker's JavaScript?
This is a fairly widespread input sanitization failure (essentially a special case of common mistake #1 ). An attacker gives your web application JavaScript tags on input. When this input is returned to the user unsanitized, the user’s browser will execute it. It can be as simple as crafting a link and persuading a user to click it, or it can be something much more sinister. On page load the script runs and, for example, can be used to post your cookies to the attacker.
How to prevent HTML injection?
Prevention: There’s a simple web security solution: don’t return HTML tags to the client. This has the added benefit of defending against HTML injection, a similar attack whereby the attacker injects plain HTML content (such as images or loud invisible flash players) – not high-impact but surely annoying (“please make it stop!”). Usually, the workaround is simply converting all HTML entities, so that <script> is returned as <script>. The other often employed method of sanitization is using regular expressions to strip away HTML tags using regular expressions on < and >, but this is dangerous as a lot of browsers will interpret severely broken HTML just fine. Better to convert all characters to their escaped counterparts.
Why do security protocols exist?
Security protocols help you write (more) correct programs, which all programmers should aspire to.
