Social engineering attacks rely on psychological manipulation rather than technical exploits to deceive individuals into revealing confidential information, providing unauthorized access, or performing actions that compromise security. The attackers take advantage of human traits such as trust, curiosity, fear, and compassion to trick their victims successfully.
Types of Social Engineering Attacks:
- Phishing: Phishing is perhaps the most common form of social engineering attack. Attackers masquerade as legitimate entities, such as banks, social media platforms, or online services, to deceive users into disclosing sensitive information. These phishing attempts often occur through deceptive emails, messages, or websites that closely resemble genuine ones.
- Pretexting: In pretexting attacks, cybercriminals create a fabricated scenario or pretext to trick individuals into divulging information or performing specific actions. For instance, an attacker may pretend to be an IT support technician and convince a target to reset their password, thereby gaining unauthorized access.
- Baiting: Baiting involves enticing victims with an appealing offer, such as free software, music downloads, or movie streaming, but the bait is infected with malware. When the victim downloads the seemingly harmless content, the malware is installed on their system, granting the attacker access.
- Quid Pro Quo: In this type of social engineering, attackers promise something in return for information or assistance. For example, an attacker might offer to provide free software in exchange for login credentials, effectively gaining unauthorized access to the victim’s accounts.
- Tailgating and Piggybacking: Tailgating occurs when an unauthorized person gains physical access to a restricted area by following an authorized individual. Piggybacking is similar but involves convincing an authorized person to let them in. Both these techniques are common in physical security breaches.
The Psychology Behind Social Engineering:
Social engineering attacks exploit certain cognitive biases and human vulnerabilities. Some key psychological factors include:
- Authority and Trust: Humans are conditioned to obey authority figures and trust individuals who appear credible or knowledgeable. Attackers leverage this tendency by pretending to be trustworthy figures to gain victims’ confidence.
- Reciprocity: The principle of reciprocity makes individuals feel obliged to return a favor or help when someone has done something for them. Cybercriminals exploit this by offering something enticing in return for information or access.
- Curiosity and Fear: Humans are naturally curious and fear missing out on essential information. Social engineers often create fake urgency or appeal to curiosity to make victims take hasty actions without considering the consequences.
- Social Compliance: People have a tendency to follow social norms and comply with requests or instructions from others. Attackers use this to their advantage to manipulate individuals into revealing sensitive information or performing actions against their better judgment.
Protecting Against Social Engineering Attacks:
While social engineering attacks can be difficult to detect, individuals and organizations can take proactive measures to reduce their susceptibility:
- Education and Awareness: Regular training and awareness programs are crucial to educating individuals about the different types of social engineering attacks and how to recognize and respond to them.
- Verification: Always verify the identity and authority of individuals making requests for sensitive information or actions before complying with their demands.
- Strong Passwords and Multifactor Authentication (MFA): Use strong and unique passwords for all accounts and enable MFA whenever possible to add an extra layer of security.
- Caution with Emails and Links: Be cautious when clicking on links or downloading attachments from unknown or suspicious sources, especially if they urge immediate action.
- Physical Security Measures: Implement physical security protocols to prevent tailgating and unauthorized access to restricted areas.
- Data Encryption: Encrypt sensitive data to ensure that even if attackers gain access, the information remains protected.

Data security refers to a set of standards, protocols, and techniques that are focused on protecting personal or organizational data from intentional or accidental destruction, modification, and disclosure. Different technologies and techniques can be applied to ensure data security. These techniques include administrative controls, physical security, logical controls, organizational standards, etc.
In order to choose the right data security protocols, it is important to understand different types of data security.
Authentication: It is the process of validating a registered user’s identity before allowing access to protected data. It is used in conjunction with authorization; the process of validating that the authenticated user has been granted permission to access the requested resources. Authentication involves a combination of ways to identify a user, such as passwords, PINS, security tokens, a swipe card, or biometrics.
Access Control: Authentication and authorization happen through access control. It is a method of guaranteeing that users are whom they say they are and that they have the appropriate access. Access control systems can include-
- Discretionary Access Control (DAC) assigns access rights based on user-specified rules.
- Mandatory Access Control (MAC) assigns user access based on information clearance.
- Role Based Access Control (RBAC) grants user access based on the user’s role and implements key security principles such as ‘least privilege’ and ‘separation of privilege’.
- Attribute Based Access Control (ABAC) assigns a series of attributes to each resource and user. The user’s attributes such as time of day, position, location, etc. are assessed to make a decision on access to the resource.
Backups & Recovery: An efficient data security strategy requires a plan for how to access the organization’s data in the event of system failure, disaster, data corruption, or data breach. This puts an emphasis on regular data backups. It involves making a copy of the data and storing it off-site or in the cloud. Also, it is important to formulate proper recovery protocols.
Encryption: Data encryption involves the translation of data into another form, or code so that it is accessible only by the authorized personnel who have the decryption key. However, it is highly important to ensure the security of decryption keys, critical management systems, and off-site encryption backup.
Data Masking: This type of data security involves the masking of original data by obscuring letters or numbers with proxy characters. The data is changed back to its original form by software only when it is received by an authorized user.
Tokenization: In this case, sensitive data is substituted with random characters that cannot be reversed. The relationship between data and its token values is stored in a protected database lookup table.

Encryption is the process of encoding information for preventing anyone other than the intended recipient from viewing it. It uses an algorithm known as a cipher to convert the information into a code that appears like random characters or symbols. This renders the information unreadable to anyone who does not have the decryption key. Same concept is applied to an encrypted communication app.
What Is An Encrypted Communication App?
An end-to-end encrypted communication app secures the messages being sent and makes sure the information is visible only to the end users – the sender and receiver.
Why Is It Important To Switch To An Encrypted Communication App?
As privacy has become an important consideration for organizations and individuals alike, securing the communications has gained leverage. Common reasons behind a leaked communication are:
- Monitoring of communications by the app providers
- Security breach by hackers/cyber criminals
A leaked communication text may cause damage to personal/organizational reputation by exposing personal/trade secrets. Additionally, communications may include the exchange of media files such as personal photos, videos, etc. Breach of these files may cause a serious threat to the parties involved.
How To Choose An Encrypted Communication App?
While it has been established that now is the time to switch to an encrypted communication app, a major question is how to choose a suitable app from the large pool of available communication apps.
In order to choose a suitable encrypted communication app, it is important to consider following points:
- Encrypted Metadata: In the context of messaging, metadata includes information such as the sender’s phone number, recipient’s phone number, date and time of the message. This information may seem trivial, but it can be used to map with whom and when the individual communicates. So, choose a communication app that encrypts the metadata along with the body of the message.
- In-App Encryption: Some communication apps do encrypt the messages being shared over the network but do not encrypt the messages stored on the device. This may cause a threat in case the device is stolen. Thus, it is important to confirm that all the messages are encrypted before being stored on the device prior to choosing a communication app.
- Online Backups: It is a common practice to back up the communications on cloud (Google Drive, etc.) to combat situations like failed/stolen devices. However, in this case, the messages are protected by a single layer of security (mostly a password). So, consider a communication app that offers an alternate solution to secure the backup.
- Security Analysis: In the case of closed source communication apps, it is practically impossible to review the code and see how well the encryption has been integrated. So, it is advisable to choose an open-source communication app that allows analysis of the security measures enforced by the app.
- Security Settings: Choose a communication app that has security-focused settings such as ‘Self-destructing messages’ that disappear after a pre-selected time, ‘Screen Security’ that prevents anyone from taking a screenshot of the conversation, etc.
