INTRODUCTION TO WEB SECURITY: STAY SECURED FROM CYBER CRIMES

October 12, 2019 Ports DB

The internet is a pool of resources and stakeholders and there exist a connection between them called a network. When you are sharing something from one end to another, you would obviously like to keep it private. Ever since the evolution of communication over the internet has begun, attackers who have a strong knowledge over this field have emerged and harm people by spreading malware, ransomware, intruding in P2P conversations and much more. Due to this, websites, emails, messengers of different apps, social media accounts are in great threats. However, technologies have been implemented to get rid of these attacks by a lot of research and development. The administrators of web servers have to constantly maintain the infrastructure and software in order to stay protected. Web security consists of 2 main parts: internal and public. This is a relative type of security which is high when only a few resources are present. Web security is the one where security for web applications and sites are applied.

Types of security threats:

Cross-site scripting– it is a kind of vulnerability that is applied by bypassing a client side script in a manner in which the scripts at the other end is manipulated or new scripts are induced into the victim’s site which is viewed by other users as though you scripted it.
SQL injection– is the one in which malicious code is sent as a query to the database with the intention to project malware and destroy the data present in it.
Denial of service (DOS) – it is the type of malware where the attacker hacks a system and makes it unavailable for the user to access the system.
Buffer overflow– it is a type of error in which the user adds the data more than the limit of the size of the buffer specified in the program. For example, if the minimum limit of adding inputs of a particular buffer is 100 and the user enters 200 inputs, instead of discarding the command, if the inputs are taken, the buffer overflow occurs.

How do we get rid of these threats?

Well, earlier, when the attackers and their strategies were investigated and found, many security engineers came up with few technological applications that could be applied to get rid of these threats as a remedy as well as a prevention measure. Firstly, black box testing and white box testing is recommended to keep track of changes happening in the application being developed and security measures have been added to test if the application built is secure. Other than these, there are other applications like firewall which acts as a barrier to let only the secure applications to enter into the system. Firewalls are being advanced by providing proxy firewalls (this type will have two firewalls) for extra security and management. One advantage of this web security measures is that the vulnerabilities will be stored for the admin to analyze the vulnerability and further improvise the security more and more.

Cybersecurity refers to a collection of practices and measures that are meant to protect the computers, networks, programs and systems against cyber-attacks. Suck kind of attacks can take the form of malware, theft of data, denial of service, tampering of data or even unauthorized access. With the ever-growing cyber threat being that of transforming the ecosystem and molding the functions of cybersecurity. The very core of cyber security always involves safeguarding information and systems from harmful cyber threats.

McAfee is one of the leading cyber security programs that is providing advanced security solutions to consumers, small and large business businesses, enterprises, governments.

The end point security solution enables one to combat fileless, zero-day, ransomware and nuisance attacks with advanced augmented defense as well as a unified management experience.

Cybersecurity in an Evolving Digital Landscape

Over the last few decades the cyberspace landscape has evolved tremendously paving way for real time, borderless exchange of information communication. The kind of technology that is being created is pervasive and has become the integral part of our daily activities. From just answering and email, sharing files over the cloud or even adjusting your thermostat with a mobile device. You are simply exploring a vast cyberspace with inestimable capabilities. Technology is rapidly expanding and so is the ever-growing link of cybercrime.

Cybersecurity Threat Landscape

Governments, commercial enterprises and nonprofit organizations around the world are facing data breaches from cyber-attacks and financially motivated actors who are looking to exploit illegally obtained data. Most of the attacks are committed using ransomware, data manipulation, wiper attacks, intellectual property, rogue software, phishing and identifiable data theft.

Cyber attacks can be deployed using a combination of multiple reasons and carrying varying degree of damage severity. There exist three categories of cyber threats. Cyber espionage which involves attacks being committed to acquire illicit access to secret information stored in digital formats or computer networks. Cyberwarfare is often politically motivated and involves nation-states penetrating other nations to cause disruption and severe damage. This kind of attacks are often committed by hackers for strategic and military purposes. Cyber-terrorism entails the disruptive use of information technology in order to further the ideological or political agenda of the terrorist group.
