Is Internet Secure?

13 mins read

As said in the previous post, and as you may have realized by now, internet is everywhere. Internet has become such a deep part of our lives that to think of a life without the internet would seem impossible. But even with all the benefits of the internet, security and privacy concerns remain.

Your identity isn’t really secure online

Internet identity

The online realm, with its vast connectivity and the convenience it offers, also poses a significant threat to the security of your identity. This risk arises from the sheer amount of personal information circulating in the digital sphere – from names, addresses, and contact details to more sensitive data like financial information, social security numbers, or medical records.

Data breaches: Large organizations often store considerable amounts of customer data. While many such organizations implement robust security measures, data breaches can still occur, leading to the unauthorized disclosure of personal information. The stolen data could include login credentials, credit card information, or more sensitive data like social security numbers. Such breaches can have far-reaching consequences, potentially leading to identity theft and financial fraud.

Phishing attacks: Phishing is a prevalent method used by cybercriminals to trick individuals into revealing confidential information. They may send deceptive emails or messages that appear to be from trusted sources, prompting you to click on a link or download an attachment. These actions can lead to the installation of malware, enabling the attacker to steal personal data from your device, or could redirect you to a fake website designed to collect your information.

Social Engineering: Social engineering attacks exploit human psychology, manipulating individuals into divulging confidential information. Cybercriminals could pose as customer service agents, technical support staff, or even friends or family, persuading you to share personal information or perform actions that compromise your data security.

Malware: Malware, such as spyware or keyloggers, can be surreptitiously installed on your device, tracking your online activities or recording keystrokes to collect sensitive information. This collected data could be used for a range of malicious purposes, including identity theft or unauthorized financial transactions.

Public Wi-Fi Networks: Public Wi-Fi networks often lack robust security measures, making it possible for malicious actors on the same network to intercept the data you send and receive. If you’re logging into personal accounts or conducting financial transactions while connected to a public Wi-Fi network, your personal information could be at risk.

In light of these threats, maintaining online privacy and securing your identity require consistent vigilance and a proactive approach. Using strong, unique passwords, enabling multi-factor authentication, being cautious of unsolicited communications, regularly updating and patching software, and using a virtual private network (VPN) especially on public Wi-Fi can significantly enhance the security of your online identity.

You are being tracked

Internet Tracking

It is important to understand that a substantial amount of tracking occurs during our daily online activities. Here’s an expanded view on how it’s done:

Cookies: Cookies are tiny pieces of data stored on your computer by your web browser at the request of the websites you visit. They allow these websites to remember you, keeping track of your visits, your actions on the site, and even your preferences. While cookies are essential for things like staying logged into your accounts or keeping items in your shopping cart, they can also be used to track your online behavior over time, often for advertising purposes.

Advertising Networks: Online advertising networks play a significant role in the digital tracking landscape. They use cookies and similar technologies to track your behavior across the many sites they serve ads on. This information is used to build a profile of your interests, allowing advertisers to serve you targeted ads that align with those interests.

Social Media Platforms: Social media platforms like Facebook, Twitter, or Instagram keep tabs on your activities within their networks, tracking the content you like, share, or comment on, the accounts you follow, and the information you provide in your profile. They may also use tracking technologies to monitor your behavior across other websites and apps, even when you’re not logged in.

Internet Service Providers (ISPs): ISPs have the ability to track your online activities since all your internet traffic flows through their servers. While many ISPs claim that they respect their users’ privacy, they do have the capacity to log your internet history and could potentially sell that information to advertisers, unless there are laws prohibiting such practices.

Mobile Apps: Many mobile apps track your activities within the app, collecting data on the features you use, how long you use them, and even crash reports when something goes wrong. Some apps also track your location, gather data from your device’s sensors, or access information from other apps, depending on the permissions you’ve granted them.

Search Engines: Search engines like Google keep track of your search queries, the links you click on, and even your location at the time of the search. This data helps to personalize your search results, but it also contributes to your online profile, which can be used for targeted advertising.

To mitigate such tracking, you can take steps such as regularly clearing your cookies, using incognito or private browsing modes, installing browser extensions that block trackers, adjusting your social media privacy settings, and being mindful of the permissions you grant to mobile apps. Nonetheless, while these actions can help, they may not eliminate all forms of online tracking.

Your internet access is logged

Internet logging

It is essential to comprehend that each digital footstep you take is potentially being recorded and logged. Let’s delve into it more extensively:

Internet Service Providers (ISPs): As mentioned previously, your ISP has visibility of your internet traffic since all data must pass through their servers to reach its destination. This means they have the capability to log every website you visit, every file you download, and every email you send. While most ISPs claim they don’t use this data for nefarious purposes, they can retain this information for a variety of reasons including troubleshooting network issues, monitoring for illegal activity, and even selling anonymized user data to advertisers in some cases.

Website Logs: When you visit a website, the server that hosts that site typically logs certain information, such as your IP address, the date and time of your visit, the pages you accessed, the device and browser you’re using, and even the website you came from. While this data is often used for analyzing site traffic and improving user experience, it could also be used to track your behavior over time.

Workplace Monitoring: If you’re using a network provided by your employer, it’s likely that your online activities are being logged. Companies often monitor employees’ internet use for a variety of reasons, such as ensuring productivity, preventing inappropriate content access, protecting company secrets, and complying with legal regulations.

Government Surveillance: In some countries, government agencies have the power to monitor and log citizens’ online activities. This can range from targeted surveillance of individuals suspected of criminal activities to broad collection of metadata for intelligence and security purposes.

Public WiFi Networks: When you’re connected to a public WiFi network, such as at a coffee shop or airport, the provider of that network could potentially log your internet activity. In some cases, this data might be used for marketing or advertising purposes.

VPN Providers: While using a Virtual Private Network (VPN) can provide a degree of anonymity and privacy, keep in mind that your VPN provider can see and potentially log your internet activity. Always ensure to use a trustworthy VPN provider, preferably one that maintains a strict ‘no-logs’ policy.

While the fact that your internet access is logged might sound alarming, it’s crucial to remember that there are steps you can take to protect your privacy online, such as using encrypted connections (HTTPS), VPNs, and privacy-focused browsers and search engines. However, it’s equally vital to stay informed about the potential privacy risks inherent in our increasingly connected world.

Your emails are not really private


Emails, for most users, are an intimate medium of communication, mirroring the one-on-one exchanges of a private conversation. Yet, the reality is less confidential. Unless encrypted, emails traverse the network in plain text, allowing any intercepting parties to read their contents. Furthermore, some email service providers scan emails for keywords to generate targeted advertisements. In certain situations, legal processes could also grant government agencies access to your email records.

Third-Party Access: When you send an email, the message doesn’t go straight from your device to the recipient. It typically passes through several servers operated by Internet Service Providers (ISPs), email service providers, and possibly network administrators (in the case of corporate networks). Each of these entities has the potential to access, read, and even store your email messages. While reputable service providers usually have strict privacy policies in place, the potential for access remains.

Email Interception: While in transit over the network, emails are susceptible to interception, particularly if they are not encrypted. Unencrypted emails can be likened to postcards, where anyone who gets access to it can read the contents. Cybercriminals can employ various tactics, such as man-in-the-middle attacks, to intercept and read your email messages.

Data Breaches: In recent years, several large email service providers have suffered data breaches, resulting in the exposure of user data, including the contents of email messages. This underlines the fact that storing private information in emails carries a risk, as the security of that information is largely out of your control.

Email Scanning: Some email providers may scan your emails to serve targeted advertisements. For instance, Google announced in 2017 that it would stop scanning emails for Gmail users to target ads. However, this practice may still be prevalent among some providers, leading to potential privacy concerns.

Legal Access: In certain situations, law enforcement agencies may legally access your email data. This could be with a warrant, subpoena, or national security letter, depending on the jurisdiction and the specifics of the situation.

Work Email Accounts: If you’re using your work email account, it’s important to remember that your employer has the right to monitor your communications. Most companies have policies in place that outline the acceptable use of corporate email accounts, and violation of these policies could result in disciplinary action.

While these points might give the impression that email privacy is a lost cause, it’s crucial to understand that there are measures you can take to protect your email communications. Using encrypted email services, enabling two-factor authentication, and being cautious with the information you share via email are all effective strategies for enhancing email privacy.

The internet is full of bad people


Cybercriminals, online bullies, trolls, and purveyors of hate speech and disinformation – the internet, much like the physical world, hosts an array of ill-intentioned actors. Leveraging the perceived anonymity and wide reach of the internet, these individuals or groups can wreak havoc on unsuspecting users. From deploying malware or phishing scams to spread harm or extract valuable information, to propagating harmful ideologies or fake news to sow discord or manipulate public opinion, these bad actors constitute a significant dark side of the internet.

Cyber Criminals: Cybercrime is a vast and growing problem on the internet. These nefarious individuals or groups use sophisticated techniques to commit offenses including identity theft, financial fraud, stalking, bullying, hacking, and spreading malware. Their tactics are continually evolving, making it imperative for individuals and organizations to maintain robust security measures.

Hackers: While not all hackers have malicious intent, a significant portion of them do. These individuals exploit vulnerabilities in software and hardware, breach security systems, and gain unauthorized access to sensitive information. They may engage in activities ranging from simple pranks to severe criminal activities such as stealing credit card information, committing corporate espionage, or launching cyber-attacks on critical infrastructure.

Scammers: The internet is rife with scammers who use various techniques to trick people into revealing sensitive information or sending money. These can include phishing emails, fake websites, romance scams, lottery scams, and more. They typically rely on social engineering techniques to manipulate victims into falling for their schemes.

Online Predators: Online predators are individuals who exploit vulnerable people, often for sexual or violent purposes. This is a particularly significant concern for children and teenagers, who may be targeted by predators on social media platforms, chat rooms, and online gaming communities.

Trolls and Cyberbullies: Internet trolls and cyberbullies are individuals who engage in harmful online behavior with the intent to upset, harass, or cause distress to others. This can include posting inflammatory or off-topic comments to provoke others, spreading rumors or false information, or engaging in personal attacks.

Data Brokers: These entities, while operating legally, collect, analyze, and sell huge amounts of personal data, often without the explicit consent or knowledge of the individuals concerned. This practice can lead to privacy concerns and contribute to invasive targeted advertising.

Despite the presence of these negative elements, it’s important to remember that the internet also facilitates many positive interactions and provides valuable resources. To navigate the digital world safely, users should cultivate a strong understanding of online risks, employ security measures such as antivirus software and firewalls, and exercise caution when sharing personal information.

Most passwords are weak


Cybersecurity experts have long harped on the importance of strong, unique passwords, yet many individuals continue to fall short on this count. Some common pitfalls include using predictable or easily guessed information such as birthdays, pet names, or even ‘password123’. Other problematic practices include using the same password across multiple platforms, and neglecting to update passwords regularly. These mistakes make it significantly easier for cybercriminals to crack passwords and gain unauthorized access to personal and financial data.

Password Reuse: One of the most common mistakes people make is using the same password for multiple online accounts. This means that if one account is compromised, all others with the same password are also at risk. Despite the serious security risks involved, many people continue to reuse passwords simply because it’s easier to remember just one or two.

Predictable Password Choices: Many people choose passwords that are easy to remember, such as birthdays, pet names, or even ‘password123’. Cybercriminals are well aware of these habits and will try these kinds of simple, easily guessed passwords first. What’s more, there are programs capable of cracking such passwords in mere seconds.

Lack of Complexity: A strong password should include a mix of uppercase and lowercase letters, numbers, and special characters. However, many people use simple, straightforward passwords. These can be easily cracked using brute force attacks, where an attacker uses a computer program to try all possible password combinations until they find the one that works.

Not Changing Passwords Regularly: Many people set their passwords when they create an account and then never change them. While it can be a hassle to update and remember new passwords, doing so regularly is a critical part of maintaining secure online accounts.

Ignoring Two-Factor Authentication: Two-factor authentication (2FA) is a security measure that requires users to provide two different types of identification to access an account, such as a password and a code sent to their phone. Despite the additional layer of security it provides, many users disable 2FA due to the minor inconvenience it poses.

Writing Down Passwords: In an attempt to remember complex passwords, some people resort to writing them down. This practice can easily lead to passwords falling into the wrong hands, particularly if they’re stored in an unsecured manner like on a sticky note attached to the computer.

To mitigate these issues, it’s highly recommended to use a password manager, which can generate and store complex, unique passwords for each of your accounts. Additionally, taking advantage of multi-factor authentication and regularly updating passwords can significantly enhance your online security.

Free WiFi isn’t secure WiFi


The convenience of free WiFi networks at cafes, airports, or other public spaces is undeniably appealing. However, these networks are often unencrypted, leaving data you transmit, such as login credentials or credit card information, vulnerable to interception. Cybercriminals also occasionally set up fake WiFi networks with names similar to legitimate public WiFi, deceiving users into connecting and potentially revealing sensitive data.

Unencrypted Networks: When you use a free WiFi network, particularly those without a password, the data you send and receive may not be encrypted. Encryption scrambles your data into a code so that it can’t be understood by anyone who intercepts it. However, on unsecured networks, anyone with a bit of technical knowledge could easily intercept and read your data.

Man-in-the-Middle Attacks: This type of cyber attack involves an attacker intercepting and potentially altering the communication between two parties who believe they are communicating directly with each other. On a free WiFi network, this could mean an attacker reading your emails, seeing which websites you visit, and even capturing your login details.

Rogue Hotspots: Some cybercriminals set up their own WiFi networks that mimic legitimate free WiFi networks, such as those offered by coffee shops or airports. When users connect to these rogue hotspots, the criminals can monitor everything they do online, capturing valuable personal and financial information.

Malware Distribution: Cybercriminals can also use unsecured WiFi networks as a means to distribute malware. If you allow file-sharing across the network, the attacker can easily plant infected software on your device.

Lack of Network Management: Most free WiFi networks aren’t actively managed. Network security requires regular updates, active firewalls, and constant monitoring – all of which are typically missing from free WiFi networks.

While free WiFi networks provide convenience, they also pose significant risks to your personal and financial information. It’s crucial to take protective measures when using such networks – use a virtual private network (VPN), keep your firewall active, only share data over secure websites (https), and always keep your system and antivirus software up to date.

No one governs the Internet


The internet, being a decentralized network, lacks a single governing body. While organizations such as the Internet Corporation for Assigned Names and Numbers (ICANN) or the Internet Engineering Task Force (IETF) establish standards or protocols, their influence is advisory rather than regulatory. This absence of centralized control means that enforcing uniform laws or standards across the internet is challenging, resulting in disparities in access, security, and censorship across different geographical regions.

Decentralized Structure: At its core, the internet is a global network of networks, all connected but none centrally controlled. Its very design is based on decentralization, meaning there’s no central authority, organization, or government that governs how it operates or what content it hosts.

Shared Standards and Protocols: The smooth operation of the internet relies on shared protocols and standards. This includes things like TCP/IP for routing and transmitting data, HTTP for sharing web content, and DNS for managing domain names. These standards are developed and maintained by voluntary organizations like the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C).

Internet Service Providers (ISPs): ISPs play a crucial role in the functioning of the internet, offering the physical infrastructure and services to connect users to the internet. Yet, while they can control access, they don’t govern the internet itself.

Role of ICANN: The Internet Corporation for Assigned Names and Numbers (ICANN) is a non-profit organization that manages the assignment of domain names and IP addresses. It plays a crucial role in ensuring the internet remains interoperable. However, ICANN does not control content on the internet.

Country-Based Regulation: While the internet as a whole is ungoverned, individual countries often impose their own rules and regulations about internet usage within their boundaries. This can involve censorship, surveillance, or regulation of certain online activities.

Net Neutrality: Net neutrality is the principle that all internet traffic should be treated equally, without any discrimination or preference given to certain types of content. This principle is crucial to maintaining the open and free nature of the internet, but it’s under constant debate and differs greatly by country and region.

The governance of the internet is a complex and multifaceted issue. No single entity governs the internet in its entirety. Instead, its operation depends on a diverse range of organizations, service providers, users, and regulatory bodies all playing their part. This decentralization is a strength, enabling the internet to remain a flexible and open platform for innovation and communication, but it also creates challenges for security, equity, and legality.

The internet, while a remarkable tool of connectivity and knowledge sharing, is imbued with significant security challenges. Recognizing these vulnerabilities, and taking proactive measures like using robust, unique passwords, encrypting sensitive communications, and maintaining vigilance about the data we share, can go a long way in enhancing our digital security.
