What is digital security in simple words
Digital security is a set of measures and technical means that protect your electronic devices, data and accounts from hackers, viruses and fraudsters on the internet.
Imagine that your smartphone, computer and banking applications are your home. Digital security is the locks on the doors, the alarm system and video surveillance, but for your digital world. Without these measures, any attacker can "enter" your home and steal your data, money or personal information.
Digital security covers several levels of protection: from simple measures (strong passwords, antivirus) to complex systems (data encryption, multi-factor authentication, network monitoring). Every user — from home to corporate — should understand the basics of digital security.
Main threats
- Phishing: Fraudulent emails and websites imitating legitimate services to steal passwords and bank card data.
- Ransomware: Encrypts your files and demands a ransom for decryption.
- Identity theft: Database leaks, traffic interception, social engineering.
- Password attacks: Brute force, credential stuffing (using leaked passwords).
- Fake Wi-Fi: Fraudulent Wi-Fi hotspots for intercepting traffic.
Protection methods
- Strong passwords: Long (12+ characters), unique for each service, using a password manager.
- Multi-factor authentication (MFA): An additional level of protection — password + code from SMS or an app.
- Encryption: Data protection at rest (disk encryption) and in transit (TLS/HTTPS).
- Antivirus and firewall: Detection and blocking of malware.
- Updates: Timely installation of operating system and application updates.
- Backup: Regular creation of data copies for recovery after attacks.
Digital security for business
For organizations, digital security includes additional measures: security policies, employee training, incident monitoring (SOC, SIEM), auditing and compliance with regulatory requirements (152-FZ, 187-FZ).
