How to Protect IoT Devices in Critical Infrastructure Networks

Cybersecurity leaders consistently rank passwords among the top concerns, recognizing them as critical gateways to sensitive data but also as prime targets for malicious entities. As we progress through Cybersecurity Awareness Month, the focus sharpens on the importance of robust password security and the methods to enhance their protection.
Passwords have a rich history, dating back to ancient times when they were used as secret codes during wars or gateways to confidential gatherings. As computers and the internet emerged, these secretive codes found a new role. They became digital safeguards, crucial for protecting organizational data from threats.
In modern systems, instead of storing actual passwords, a process called “hashing” is employed. This transforms the password into a unique string of characters. When users log in, the system hashes the entered password and checks if it matches the stored version. This way, even if malicious actors access a system’s stored data, they see only these hashes, not the actual passwords, adding an extra layer of security.
However, every defense comes with vulnerability. Cybercriminals, ever-adapting, have learned to capitalize on password-related vulnerabilities.
One major example of the dangers of compromised passwords is the 2021 Colonial Pipeline ransomware attack. Cybercriminals exploited a compromised password to gain unauthorized access to Colonial’s systems. The result? The US’s largest fuel pipeline was forced to shut down operations, leading to significant fuel disruptions and price hikes across the Eastern seaboard.
Alarming as it is, the statistics around password security paint a worrisome picture:
To effectively combat password-related threats, it’s vital to recognize the array of attack methods used by cybercriminals. We’ve compiled a comprehensive list of the most prevalent password attack types. By understanding these threats, organizations not only empower their employees with awareness but also fortify their cyber defenses. After all, knowing is half the battle.
1. Brute Force Attack
In this straightforward yet resource-intensive approach, attackers use software to try every conceivable character combination until the right password is found. Depending on the length and complexity of the password, this can take a significant amount of time and computing power.
2. Dictionary Attack
Attackers employ a list of commonly used passwords or words, the so-called “dictionary.” While faster than brute force, it relies on users picking commonly known or easily guessable passwords. The list can be customized with names, slang, pop culture references, and other potential password components.
3. Rainbow Table Attack
A rainbow table is essentially a list prepared in advance, filled with unique codes that correspond to possible passwords. Instead of constantly trying to convert guessed passwords into these codes (a process known as hashing), attackers can quickly check the table to see if a code matches a known password. This makes breaking in much faster.
4. Credential Stuffing
Leaking of large databases of user credentials is, unfortunately, a common event. Attackers take these username-password pairs and use automated tools to try these credentials on multiple platforms, banking on users reusing passwords.
5. Keylogger Attack
Here, malicious software or hardware secretly logs keystrokes on a victim’s device. Advanced keyloggers can even capture screen information, clipboard data, and mouse clicks, further compromising the user’s information.
6. Phishing Attack
Crafted emails, appearing genuine and from trustworthy sources, aim to deceive users into revealing their credentials. These often lead victims to well-designed fake web pages that mirror real login portals.
7. Man-in-the-Middle Attack
Attackers secretly intercept and relay communication between two parties. They can alter the communication or use it to gather sensitive data. This can happen through Wi-Fi eavesdropping or even through sophisticated software interventions.
8. Offline Cracking
Instead of trying to infiltrate a secure online system, attackers might steal a database containing hashed or encrypted passwords. With the data in their possession, they can attempt to decrypt these passwords without any online systems alerting on multiple failed attempts.
9. Social Engineering Attack
This psychological manipulation method convinces individuals to reveal confidential information. It might involve impersonation, false scenarios, or even building a rapport with the victim over time. It highlights the human as the weakest link in security chains.
10. Shoulder Surfing
An attacker simply watches a user enter their password. Though rudimentary, it can be effective, especially with the aid of hidden cameras in sensitive areas like ATMs or office spaces.
11. Password Spraying
Instead of trying to guess many passwords for one user, attackers try a single commonly-used password (like “123456”) against many accounts on a system. It’s a broader approach, hoping to catch those using the most basic passwords.
12. Hash Collision Attack
The objective is to find two different pieces of information (like two different passwords) that, when processed, result in the same unique code. If attackers find this pair, they can use one of them to gain access, even without knowing the actual intended piece of information the system expects.
The frontline of cybersecurity features passwords. Yet, a password’s existence isn’t a guarantee of security. Its strength, uniqueness, and the protective mechanisms behind it are the true determinants.
Here’s how organizations can turn your passwords from mere gatekeepers into impenetrable fortresses:
While traditional passwords present certain security challenges, the shift towards password-less authentication is gaining momentum. This method bolsters security by verifying users through unique identifiers, be it biometrics such as fingerprints or voice, time-based passcodes like those from Google Authenticator, one-time pins sent to phones, or push notifications for immediate access approval.
Despite its resistance to common password attacks and added security notifications, this authentication approach can be more intricate and sometimes less user-friendly, relying on external systems for optimal functionality.
As we navigate the evolving landscape of cybersecurity, the emphasis remains on striking a balance between robust security and user convenience.
