The practice of protecting information systems from unauthorized access, use, disclosure, disruption, modification, or destruction, critical for safeguarding data in the digital age.
There is much confusion as to what a blockchain is and its dichotomy with a database. A blockchain is actually a database because it is a digital ledger that stores information in data structures called blocks. A database likewise stores information in data structures called tables. However, while a blockchain is a database, a database is not a blockchain. They are not interchangeable in a sense that though they both store information, they differ in design. There is also a difference in purpose between the two, which is perhaps what is not clear to those who want to understand why blockchains are needed and why databases are better suited for storing certain data.

According to research by GlobalWebIndex, in 2018, around 25% of Internet users have used a VPN service. There are several reasons for this spike in popularity, which you can read about in my previous article. One of the main reasons is the ability to bypass geo-blocks and gain access to, for example, a full Netflix library.
We use passwords to access personal information and user accounts. With so many applications requiring passwords (e.g. online banking, shopping and social media just to name a few), it can be hard to track and at worst remember. Some applications require users to change their passwords every so often, and that can lead to users forgetting them or getting careless by writing down their password on a piece of paper. That piece of paper can later be misplaced which can lead to worse things. The problem with requiring frequent password changes and applying complexity to passwords is that it can become more complicated for users.

Staying safe on the internet has grown harder over the past few years as both technology and hackers have developed. Recently though, hackers are gaining an edge by not just manipulating the tech, but by manipulating the users themselves. In 2018, weak or stolen passwords were tied to over 80% of security breaches and in 2019, there were over 150,000 security incidents and nearly 4,000 confirmed data breaches. In 2020 alone, more than 15 billion stolen credentials were up for sale on the dark web. All this data points out the fact that our current way of protecting data is flawed, but making a new way to protect it while still maintaining security and convenience is a high mark to hit.

SIEM stands for "Security Information and Event Management". It is a set of tools and services that offer a holistic view of any organisation's information security. It works by combining two technologies: Security information Management(SIM), which collects data from the log files and runs an analysis on the security vulnerabilities and reports them, and Security Event Management(SEM) which monitors any system on a areal-time basis and also keeps the network admins notified about the threats. SIEM is used to identify threats and anomalies in the network, cyber attacks from gigs of data.
