We all understand what it means to "read between the lines" metaphorically. Still, before the advent of modern technology, individuals occasionally took it literally by secretly putting notes in invisible ink between the lines of a seemingly regular letter.
The process by which the author of a message conceals secret information within something that appears benign on the surface is called steganography, and it dates back to the dawn of writing. Unlike cryptography, which scrambles the message to render it incomprehensible without the decryption key, steganography's objective is to conceal the message's very existence from prying eyes. As is the case with many other methods of information concealment, steganography is currently applied in digital technology as well. Today, you can even opt for a cyber security course that will help you to know the ins and outs of security.
What is Steganography?
Steganography is a term that refers to a technique used to conceal information. If steganography is to be defined, it can be defined as the activity of concealing hidden messages within or over anything that is no secret. It is just the process of concealing a bit of text within another text, image, or audio file from attack. The message could be a text message or a script contained within a document or image file. Steganography is a method of covert communication whose primary objective is to conceal and deceive. Any media can be used to disguise the message. It is distinct from cryptography, which is a science concerned with ensuring privacy. Steganography is defined as a technique for concealing data administration that does not need scrambling or the use of a key or code, this is covered in cyber security diploma course in a lot of online courses.
How is Steganography Applied in the Modern Era?
In modern digital steganography, data is first encrypted or obfuscated in some way and then placed into data administration that is part of a certain file format, such as a JPEG picture, audio, or video file, using a special algorithm. The secret message can be placed in numerous ways into conventional data files. For example, one method is to conceal data in bits representing identical colour pixels repeated in a row in a picture file. By applying the encrypted data invisibly to this redundant data, the outcome is a picture file that seems identical to the original. Still, it contains "noise" patterns created by ordinary, unencrypted data.
A frequent steganography application is the addition of a watermark — a brand or other identifying data concealed within multimedia or other content files. Watermarking is a technique that internet publishers frequently employ to determine the origin of media assets discovered being copied without permission.
While steganography has a variety of applications, including embedding sensitive information into file formats, one of the most popular is embedding a text file within an image file. When this is done, no one viewing the image file should tell the difference between the original and encrypted file; this is accomplished by placing the message in the data file with less significant chunks. This procedure can be carried out manually or by utilizing a steganography tool. For more knowledge regarding the tool, you can check out and opt for the right cyber security diploma course.
Software for Steganography
Steganography software is used to conceal data in a variety of ways, including encoding the data to prepare it for hiding inside another file, tracking which bits of the cover text file contain:
● Hidden data.
● Encrypting the data to be hidden.
● Allowing the intended recipient to extract the hidden data.
Tool that conceals images within other image files; and Scripture, a command-line steganography tool.
Conclusion
Hackers are utilizing a technique known as steganography (derived from the Greek term "steganographic") to deceive internet users and smuggle dangerous content across the use of firewalls, scanners, and security malware software. Unlike encryption, which obscures data to make it incomprehensible, steganography conceals the existence of content by embedding it in something else. Thus, it is more of a notion than a method of data distribution via covert methods, making it easier to execute in various inventive ways.
Global healthcare cyber security market size is expected to reach nearly USD 10,848.87million by 2022, according to a new report by Grand View Research, Inc. Key factors attributing to the growth of the market include the increasing incidences of cyber attacks for misuse of electronic patient health records (E-PHR), social security records, IP theft, and others.
On previous encounters it was witnessed that cyber attacks were focused on stealing, financial information, billing information, and bank account numbers using stolen devices with un-encrypted data, phishing and spam mails.
Furthermore, these organizations face internal threats due to factors such as the use of cloud services, unsecure networks, employee negligence, bring your own device (BYOD), lack of internal identification and security systems, stolen devices with un-encrypted files.
Healthcare cyber security market is segmented by, type of threat into malware, ddos, advanced persistent threat (apt), spyware, lost and stolen devices, others.
Security information and event management (SIEM), risk and compliance management, DDoS mitigation, antivirus, antimalware, identity and access management, intrusion detection system (IDS)/intrusion prevention system (IPS) and others are the solutions included in the scope of the study.
Market dynamics in this sector are dependent on the type of threat, effectiveness, and frequency of attack, ability to detect and destroy.
The global cyber warfare market is expected to reach USD 91.75 billion by 2025, according to a new study by Grand View Research, Inc.
The increasing number of cyber-attacks are emerging as a significant threat across the globe.
The dependence of organizations on information technology and the valuable & sensitive nature of digitally-stored data have raised the stake for cyber attackers whose primary motive is to disrupt economic growth and gain technological advantages by stealing intellectual properties of national defense forces.
Increased concern towards catastrophic nature of cyber warfare and national security are factors anticipated to drive the market over the forecast period.Cyberspace disruption capabilities have outstripped nation's focus on terrorism.
The increasing cyber-attacks such as abusing digital infrastructure and network infiltration within industries and defense sector have led the government to focus more on cyberspace vulnerabilities.
In light of the growing cyber incidence, increased cybersecurity spending is proposed, and warfare units are established by the governments aimed to protect nation's sensitive information and deter potential of the cyber threat.
