What is Data Encryption Standard (DES)?
Synopsis
The Data which is encrypted by symmetric key method is called Data Encryption
Standard (DES). It was prepared by IBM Team in 1974 and declared as national
standard in 1977. Government was also using cryptography, especially in
diplomatic communication and military. Without cryptography it’s difficult to
interpret military communication. Cryptography was also used in commercial
sector. Federal Information Processing Standard (FIPS) was also working on DES.
FIPS was integrated with comput

How to Use Your Threat Model as a Guidepost for Security
The threats you face are unique to your company's size, industry, customer base,
and many other factors. So your approach to protecting your
organization's digital data should be unique, too.
In this post, we’ll cover a framework to develop an effective threat model that
will fits your organization's unique needs.
The Factors that Determine Your Unique Threat Model
There are many factors that can determine your threat model. And while this will

How to Prevent XSS Attacks
In my last post, we covered what is XSS and why it’s so hard to prevent, which
can seem overwhelming, given what we know now. With even major web sites making
mistakes should the rest of us just give up unplug our internet connections and
go read a book? Of course not, there are a number of techniques that the
community has developed to mitigate the risks of XSS. Here’s what we can do to
prevent XSS attacks.

Exploring SHA-1 (Secure Hash Algorithm)
Synopsis
In computer cryptography, a popular message compress standard is utilized known
as Secure Hash Algorithm (SHA). Its enhanced version is called SHA-1. It has the
ability to compress a fairly lengthy message and create a short message abstract
in response. The algorithm can be utilized along various protocols to ensure
security of the applied algorithm, particularly for Digital Signature Standard
(DSS). The algorithm offers five separate hash functions which were created by

Triple DES, 3-DES Network Encryptor
Synopsis
Triple Data Encryption Algorithm (3DES) is an advancement of the popular DES
standard. 3DES utilizes symmetric key block cipher. Using three unrelated 64
bit keys, 3DES was created to encrypt 64 bit blocks of data. In DES block,
each key is utilized as an input. Without creating an entire new cryptosystem,
3DES can highlight the apparent defect in DES. Through exerting the algorithm
three times in progression with three unlike keys, 3-DES simply enhances the key
size of DES. As DES

10 Steps Towards the Path of Better Security for Your Business
Information security is hard. So hard, in fact, that many choose to ignore it as
an intractable problem, and choose to ignore it wherever possible. They use the
same password everywhere, carry sensitive data around on unencrypted laptops
which they then leave on public transportation, run old applications on old
operating systems, and a plethora of other such security issues.
In an alarmingly-large number of data breaches, attackers do not resort to

Setting Up and Managing a Bug Bounty Program
Synopsis
Bug bounties have become mainstream and rightfully so. They offer a method to
access and harness the intelligence of varied set of expert hackers and security
researchers without having to incur the cost of hiring an army of security
professionals. The main advantage though is that one can keep a step ahead of
the malicious hackers. This article talks about how to setup a bug bounty
program and some of the pitfalls to watch out for.
