Today almost everything we do is connected to the internet and our lives are highly digitalized, personal and professional. We make deposits from our phones, store our memories in the cloud, work with coworkers everywhere, and turn our lights, TVs and sprinklers on and off with our voices. This hyper-connectivity is extremely convenient, but also presents us with a new environment of digital threats.
There is still a mindset today that cybersecurity is limited to the corporate realm and a specialized area for IT departments. In fact, individuals are as much of a target for modern-day cyber threats as are large companies. Cybersecurity knowledge and best practices in digital health are no longer discretionary, but a necessary life skill.
Let’s start our journey into cybersecurity and its core fundamentals.Let’s get started on our trip to the basics of cybersecurity.
In its essence, cybersecurity is a field that involves safeguarding computer systems, networks, devices, and programs against digital attacks, unauthorized access, theft, or damage. It is helpful to understand its key goals, and typical threat vectors, to understand how it works.
The Foundation: CIA Triad
Security engineers assess defense systems based on an inspiration model called the CIA Triad:
Confidentiality: Keeping sensitive data available, but only to those with permission to access it and protected from prying eyes.
Integrity: Ensuring that data is accurate, authentic and complete; prevent unauthorized tampering or modification.
Availability: Providing reliable access to system and data as needed by authorized users.
Each security device, whether it’s a basic alphanumeric password or an intranet-based security and firewall, is intended to support one or more of these three.
The issue of common threats to everyday users is being addressed.Common threats to the everyday user are dealt with.
The people behind a cyber attack aren’t necessarily portrayed as shady people sitting in dark rooms pressing buttons and hitting keys. Most of the common vulnerabilities use known techniques based on simple human psychology and common practices:
Phishing- Any email, text message or direct message that appears to be coming from a trusted organization and asks for passwords, credit card numbers or other personal information that can be used to perpetrate identity theft.
Malware and Ransomware: Malicious software that infiltrates devices, tracks keystrokes, takes files, or locks up devices until a monetary ransom is paid.
Credential Stuffing: Cybercriminals use leaked username and passwords from one site and try over other frequently visited websites.
Unsecured Wi-Fi Exploits: An eavesdropping attack on an open Wi-Fi network where an attacker gains access to intercepted data from unencrypted communications within the network, usually from people in a coffee shop.
- The importance of Cybersecurity to all people.
The misguided can say, “I am not well-known, rich or powerful – why would a hacker pick on me?” But cybercriminals do not (usually) target the individual because of their identity but solely because of what they have, what they can do, and what they can access.
Safeguarding Financial Assets and Identity
One lost credential can lead to an attacker gaining access to your key financial accounts, digital payment wallets, or investment portfolios. Identity theft can result in years of bureaucratic chaos, in addition to the financial theft. Fraudsters can also establish credit cards or loans in your name, or file phony tax returns, which can cripple your credit score and financial autonomy.
Preserving Intimate Privacy and Personal Data
Digital devices are personal records of our lives. They contain sensitive health information, private communications, work correspondence, home addresses, and private pictures. If personal data is exposed or misappropriated online in a data breach, it can result in serious embarrassment, blackmail or damage to the reputation of the individual or organization.
Avoid the Ripple Effect to Others (Avoid getting involved in other people’s problems)
If your personal account is hacked, you are not alone. Email accounts and social media profiles are often exploited by hackers to spread malicious links to friends, family members and colleagues who rely on information that comes from their names. Moreover, the personal computer or cellphone on which you work can be a backdoor into your employer’s company network if that device is compromised in an era of remote working.
- Adopt Practical Cybersecurity Habits Everyone Can!
You don’t need to be a computer scientist to strengthen your online profile. By adopting just a few basic practices, you can protect yourself from most cyber risks that may arise.
Use Strong Passwords and Multi-Factor Authentication.
Using the same password on more than one website is among the biggest risks on the internet. Use a password manager to create and safely store strong, one-of-a-kind passwords for each account. Also, activate Multi-Factor Authentication (MFA) if possible. With MFA enabled, stolen credentials won’t be enough to gain access to your account, as there is a second verification step, like an authenticator app prompt or a security key.
Follow Deliberate Digital Skepticism
Be very wary of unsolicited communications. A common trick used by scammers is to create an artificial sense of urgency to encourage an impulsive response. Do not click on links (or attachments) that you do not recognize, or give out sensitive information unless you have confirmed that the sender is who they claim to be.
Ensure Systems and Devices are kept up to date.
Software and operating system patches are more than pretty; they provide critical security fixes that patch newly found holes. When you’re not updated, your phone, tablet and computer are vulnerable to exploits that are already known. Make sure that software is automatically updated for all devices and applications so that your defenses stay up to date.
A conclusion is provided at the end of the story.
Cybersecurity is not a product that can be purchased, it is a process of awareness and deliberate choice. Digital responsibility is the equivalent to locking your front door, wearing a seatbelt and keeping your physical wallet with you, and it’s essential for maintaining peace of mind in a connected world. When you incorporate some simple precautions into your daily life, you’re able to reap the rewards of technology without getting hurt or compromised.
