Security will be the main concern for users in today’s world, where the Internet has taken over each sector. The world filled with connected devices facilitates our lives and brings many safety threats.

The Internet was initially designed to connect big computers in universities, companies, and administrations. It grew exponentially when personal computers were used to remove data, spread viruses or even steal the identity of someone in the 1980s. The good news is that you can remain secure online in various ways.

Take a look at the basic threats and steps that you face to guard against.

1. phishing

Phishing is a form of social engineering attack aimed at robbing user logins, credit card credentials, and other personal financial data. In the majority of cases, these attacks come from a trustworthy source.

When you reply or follow its instructions to a phishing email, the information is sent directly to its malicious source. You can then make purchases using this information.

Most people using the internet will experience a phishing attempt at least once— after all, spam emails are commonplace — so only vigilance and caution can prevent you from becoming victims.

How to stay safe from Phishing:

  • Install software manufacturer patches as soon as they are distributed. Your best defense against the trojan and spyware installation is a fully patched computer behind a firewall.
  • Use the anti-phishing extensions available on Google Chrome and Mozilla Firefox browsers.
  • Never click on the links in unsolicited emails or ignore call-to-action emails (for example, “Your account is closed! “).
  • Search domain names or email addresses for orthographic or grammatical errors. E-mail addresses are often used by cyber criminals who resemble but are slightly modified, the names of well-known companies. For example, instead of accounts@gmall.com (” l “rather than “i “), accounts@gmail.com.

2. malware

Malware, or malicious software, is a program or file harmful to the user of a computer that is written in order to compromise the system and to steal the data which are available on the system. It may perform different functions such as stealing, encrypting, or deleting sensitive data, altering or hijacking the core functions of computing and monitoring.

In the course of internet browsing, malware is often inserted into a system through malicious email attachments or faulty “alerts “and an older or pirated version of an operating system that is not safe or upgraded and thus vulnerable to attacks.

Major Types of Malware:

  • Virus: It is the most frequent malware type. It can run and then replicate to other files and programs.
  • Trojans: A Trojan or Trojan horse is a type of malware often disguised as software. This kind of malware tends to create a safety backdoor that allows attackers to remotely monitor your activities.
  • Spyware: It’s a background hide and tracks all you do online, including your passwords, credit card numbers, surf habits, and chat. The name suggests that Spyware is a malware that is used to spy on you.
  • Keylogger: These are a special type of instruments that record your keystrokes. These data are saved and sent to the hacker who designed the data in an encrypted file. This helps the hacker to receive passwords, credit card information and chats.

How to stay safe from Malware:

  • A good antivirus is always the first way to protect yourself against malware.
  • Continue to update your software and operating system as you continue to release new protection patches.
  • Configure your antivirus to take the entire computer regularly.
  • Never download/install pirated software as it contains malware most of the time.
  • Never use the same passwords for different websites and ensure that you are protected against any brute force attack by using passwords.

3. Sql injection

In the server, this information may include any number of items, including company data, user lists, and private client details. SQL Injection( SQLi) refers to an injective attack in which an attacker may execute a SQL malicious statement that controls a Web Application Database Server.

A web attacker must first find an input in a web application that is included in the SQL query to execute malicious SQL queries against a database server.

What is SQL?

SQL is a programming language designed to manage RDBMS storage data, so SQL can be used for accessing, modifying and removing data. In addition, RDBMS may also be able to run commands from a SQL statement on the operating system in specific cases.

How to stay safe from SQL Injection:

  • This coding style makes it possible to distinguish between code and data, regardless of which user input is supplied, by using a prepared statement with a variable link( also parameterized queries).
  • The web applications developer should not simply avoid connecting to the database by using the same owner/admin account in the web applications. For different web applications, different DB users could be used.
  • In general, you should check every page’s codes for places where page contents, commands, strings, etc., can be combined with user sources.

4. distributed denial of services

These attacks were some time ago most well-known. In a distributed denial of service (DDoS) by overwhelming the target or its surrounding infrastructure with Internet traffic floods, normal traffic is disrupted for a targeted server, service, or network.

Many compromise devices, frequently distributed worldwide on what is called a botnet, launch a DDoS attack. It distinguishes itself by using an internet-link device (one network connection) in order to inundate a target of malicious traffic from another denial of service (DoS).

Since almost all companies today rely on the internet, there is a grave threat from the specter of a DoS attack.

How to stay safe from DDoS attack:

  • The key step you can take is to ensure that you have enough bandwidth to deal with traffic spikes that may result from malicious activity in all ways that DDoS attacks are avoided.
  • Make sure you spread them through many datacentres with a good load balancing system for traffic between them, to make it as hard as possible for an attacker to successfully start a DDoS attack against your servers.
  • The Network firewalls and more dedicated web app firewalls should protect your servers, and you are likely to also use load balancers.

5. malicious mobile apps

Nobody is talking about mobile security when it comes to security. Smartphones are so handy that everyone else owns them. They also bought security threats as smartphones advent in daily life.

The greatest misunderstanding that you will ever hear was the legitimacy of all applications downloaded from the Play Store or Apple Store. However, it’s not the truth. Each app in these shops is not safe. These applications may contain malicious code which could jeopardize privacy.

The following permissions should be looked at, as they may be misused with a request:

  • Accounts access: It helps to access important data in applications that need sign-in.
  • SMS permission: You can write or read SMS on the phone of the user.
  • Microphone access: All conversations can be recorded via the phone.
  • Device admin permission: It gives the app administration privileges that allow the app to access and modify all root files.

How to stay protected from malicious mobile applications:

  • Most people only access the permissions that the apps request. Try to read the service terms or realize that the app requires or does not require this particular service.
  • Check reviews and assessments of how people have experienced the use of it.
  • Do not download third-party apps.
  • Download pirated/cracked applications never again. Because the malicious code is included.

verdict

It doesn’t matter if you use the best antivirus software on the market. Only if you are updated and think twice before installing anything can you prevent yourself.

Many of the hacks can be patched. However, social engineering always represents a serious threat. The human brain has no patch. Knowledge is crucial. It is important.
