Concerns about cybersecurity are growing with the increasing popularity of smartphones, devices, and homes. There are more methods than ever for cybercriminals to access personal data, from common apps and websites to smart devices used in smart homes. With the increasing use of such smart and accessible devices, the concept of cybersecurity has also gained extra importance. So what is cybersecurity?
What Is Cybersecurity?
Cybersecurity is the practice of protecting computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. It is also known as information technology security, electronic information security, or computer security. The term is used in a variety of contexts, from business to mobile computing, and can be classified into several common categories.
- Network security is a practice to protect a computer network from intruders, such as targeted attackers or opportunistic malware.
- App security focuses on keeping software and devices safe from threats. A corrupted security system can jeopardize privacy by allowing access to stored data. Successful cybersecurity begins at the design stage, long before a program or device is built.
- Cybersecurity protects the integrity and confidentiality of data both during storage and transfer.
- Operational security includes processes and decisions for processing and protecting data assets. The permissions that users have when accessing a network and the procedures that determine how and where data will be stored or shared fall under this heading.
- Being able to maintain business continuity in high-risk situations that develop unexpectedly defines how an organization responds to any cybersecurity incident. Disaster recovery policies determine how the organization restores its operations and information in order to return to the same working capacity as before the incident.
- End-user training addresses the most unpredictable cybersecurity factor: humans. Anyone can accidentally infect a secure system with a virus by not complying with good security practices. Teaching users how to delete suspicious email attachments, not to install unidentified USB drives, and various other crucial lessons are vital to the security of any organization.
What Is Internet of Things?
The Internet of Things (IoT) refers to devices connecting to the internet. Cars, kitchen appliances, and even heart monitors can be connected via IoT. The Internet of Things is the most effective technology in terms of inter-device connectivity in the developing world in recent times. Internet of Things security is also critical in smart home security systems.
What Are The Internet of Things Devices?
Any internet-connected device that can be monitored and/or controlled remotely is considered an IoT device. Thanks to more powerful connections, almost all objects, from large to small, can be the Internet of Things devices.
What Is The Internet of Things Ecosystem?
The Internet of Things ecosystem includes all components that allow organizations, governments, and consumers to connect to IoT devices, such as remote controls, dashboards, networks, gateways, analytics, data storage, and security.
Why Cybersecurity Is a Smart Home Problem?
Smart home systems contain much more information than a computer due to their connection structure. The greater the amount of information, the more security is compromised. A smart home system can detect when individuals are at home and which room they are in. This can cause problems in many ways for people living in a house with weak cybersecurity. However, these problems do not occur with a secure system. The following are some ways to make a smart home safer:
10 Ways to Make a Smart Home Safer
- You Should Update The Router
Many malware can render the router that is used for smart home systems useless. Malicious software can breach router security and steal passwords and data. To avoid this issue, it is required to reset the router on a regular basis. Periodically resetting passwords will reduce the risks.
- You Should Set Up A Guest Wi-Fi Network
When a smart system is installed at home, it will most likely be connected to the Wi-Fi system. Connecting guests to the Wi-Fi system jeopardizes the Internet of Things security as well. A guest network should be established in order to prevent this situation. With a guest network, guests who temporarily come home can use the internet without connecting to the main Wi-Fi network. This guest network can be expanded by creating separate network IDs or SSIDs. The main network in the house is used for security elements and device management, while the guest network is simply used to connect guests to the network. This reduces the risk of any data being stolen in the event of a security breach.
- You Should Keep Passwords Strong and Secure
The first thing to do after installing an Internet of Things device should be to change the password that comes with it. One of the most common reasons for stolen data is not to change these passwords or to use simple passwords. The new password should not be the first thing that comes to mind, such as the year of birth, consecutive numbers, first and last name. It must be a secure combination of letters, numbers, and symbols.
- You Should Make the Network Completely Secure
The Wi-Fi network must be protected with a password that only you know. It is wise to use the WPA2 protocol in router settings for encryption. In this way, security can be improved. Although WEP may still be the most widely used protocol when it comes to cybersecurity, its security is substantially weaker, meaning it is more vulnerable to attacks.
- You Should Adopt Two-Factor Authentication
Two-factor authentication is a mechanism that has recently gained popularity, particularly in messengers and email services. In this system, a second security sequence is requested to authenticate after logging into this system with a user name and password. In two-step verification, it is not enough to just type the password; another password is also sent to the phone or email address to which the account is linked.
- You Should Make Software Updates Regularly
Although software updates may not seem very important, there are usually improvements in update packages that close security deficiencies. Making these updates reinforces the cybersecurity system. Smart device updates often include patches released to counter potentially weak security points. These updates also prevent new security threats that devices may be exposed to.
- You Shouldn’t Use Smart Devices on Public Wi-Fi Networks
While it may be tempting to connect smart devices to the internet everywhere, connecting to the internet on public Wi-Fi networks is a risky situation. Public networks are much more likely to have infected applications. In addition, other users using the public network can access all devices connected to the network.
- You Must Disable Unnecessary Features
Disabling unused features of smart goods is also an important step to ensure cybersecurity. A function that you are not even aware of can provide access to the device. In this way, the vulnerability is not formed due to unthinkable and unused features.
- You Should Use Biometric Authentication
Biometric identification eliminates most of the possibility of security breaches. Foreigners are also prevented from manually accessing devices with a smart lock, facial recognition, retina recognition, or fingerprint recognition.
- You Should Use a Firewall and Security Software
With strong antivirus software and a firewall, the cybersecurity system is completely secure. Firewalls monitor network traffic and filter malware. Firewalls block viruses, worms, and Trojan horses that try to enter the network, as well as prevent the data outflow from the network unless the user allows it.
