The industry of cybercrime has been increasing its pace over last years, today hunting not only small businesses (43%, according to Cybint’s research) but also targeting mega-corporations and government agencies, meaning hackers are tirelessly improving their tools in order to overcome even the highest, the most advanced data security fences. More importantly, the real value of information (namely, the buyback price that one will have to pay to redeem their stolen data) increases in proportion to the arising threats: when a decade ago the average cost of a data breach was less than $500, in 2020 those numbers are expected to exceed $150 million on the average according to the data presented by IT consultant firm OneClick. With all that in mind, how do you like the fact a hacker attack occurs every 39 seconds?

All the above was not mentioned to frighten: it’s only supposed to emphasize the significance of being more than ever diligent when it comes to potential risks and means intended to minimize them. But let’s take it in order.


Being a vital aspect of IT industry, data security represents a complex of protective measures — such as key management, tokenization, and data encryption practices — to assure one’s crucial data (personal, financial, or business-related information), or identity won’t get compromised, corrupted or stolen by malicious actors or software. Its main goals are best explained with the thing called CIA principle:

  • confidentiality: prevent the disclosure of sensitive data from unauthorized people, processes or resources
  • integrity: protect the data from intentional or accidental modifications
  • availability: assure that system and information it stores are accessible by authorized users when needed

Data security, however, is not just important for organizations — but also personal computers, laptops, tablets, and mobile devices which could be the next tee of cybercriminal attacks.

Cyber Attacks: Most Common Techniques

There are plenty of algorithms cyber-attacks are performed through. Of course, you don’t need to be familiar with all of them (especially if there’s a cybersecurity expert in your workforce — hiring whom, by the way, would be a sure thing to do), but having at least basic knowledge as to the possible threats might help you choose a proper countermeasure to protect your information. Here are three of the most common cases:

#1. The ways malware is infecting users’ computers are well-known: through attachments in spam emails, via executable files, within free programs and applications, by redirecting people on contaminated websites, etc. But what exactly happens during an attack of malicious software? Well, the answer is simple: identity theft. Intellectual properties, credit card numbers, bank account information — malware attacks are dangerous primarily because of the data it could use to make money off.

#2. Direct-access attack refers to a method where a hacker is able to gain access to one’s computer, and then directly download data from it; during this attack, an intruder may modify the software and add key loggers, worms, etc. — in order to compromise the security of the whole system.

#3. Finally, a backdoor attack implies an algorithm that is used as a tackle to bypass system security and keep the connection while staying undetected.

But in case you’re reading this article when your data has already been corrupted or encrypted, don’t rush to panic — better contact Salvagedata recovery team: with more than a decade of experience in the data recovery field, they own plenty of advanced techniques and tools to redeem and restore data which other recovery labs claimed unrestorable. After all, having a reliable plan B in case of data loss is just wise, isn’t it?

Data Security Types

Email Security

As it must be seen from the name, Email Security is the type including various protective means designed to secure the access and content of an email account or service. Basically, the electronic correspondence includes multiple step-by-step procedures that begin with the message’s structure; thus, in order to provide protection from unwanted access at every stage, the service provider implements email security software to safeguard email accounts and data from hackers.

Network Security

The network layer security accommodates a multitude of subnetwork technologies, cryptographic techniques and interconnection strategies to protect TCP/IP (Internet protocol); basically, it’s purpose is to implement security services into a layered communications architecture, and hence to secure emails on the internet. This type includes various encryption techniques for the traffic of the website (SSL/TLS), network security (IPSec), and for email (PGP program).

Data And System Security

Data security implies the efforts could be taken to guarantee that the stored information won’t be deliberately accessed, unintentionally changed, deleted, or abused in any other way as a means of illegal profit. System security’s purpose is to protect everything that is ensured in an enterprise’s networks and resources. Simply put, data security’s goal is protecting the information — whereas system security is meant to safeguard the information stored on devices and on the network.

IPSec Protocol

The last but not the least, IPSec Protocol was developed to guard the connection between two devices through authentication and encryption of the data packets. This type implies the utilization of cryptographic security services that allow protecting communications over Internet Protocol (IP).


In our high-tech era, it became nearly impossible to protect yourself from all the cyber attacks and potential threats — mostly because they new ones are developed on a daily basis by millions of hackers all across the globe. However, knowledge is the power: proper information background may once save your business from a prolonged downtime, or severe material losses caused by intruders.
