What is Security system  and  How security works on Internet.

What is Security system.

In this instance, we're talking about home and internet security systems, which are networks of integrated electronic devices working together with a central control panel to protect against burglars and other potential home and Internet intruders.

Internet security is a specific program that is designed to protect the data that is sent to internet by us. This includes various kinds of encryption such as Pretty Good Privacy (PGP). Other aspects of a secure Web setup includes firewalls, which block unwanted traffic, and anti-malware, anti-spyware and anti-virus programs that work from specific networks or devices to monitor Internet traffic for dangerous attachments.

The most basic definition of any security system is found in its name. It is literally a means or method by which something is secured through a system of interworking components and devices.
A typical home and Internet security system includes:
  • spywares
  • Phishing
  • Motion sensors, both interior and exterior
  • Wired or wireless security cameras
  • Malwares
  • A control panel, which is the primary controller of a home's security system
  • Door and window sensors
  • Hackers

  • A yard sign and window stickers
  • A high-decibel siren or alarm.

How does Internet security works.

Internet and web browsers have their security systems called HTTP and HTTPS that combine the systems certificates that provide us a secure connection. You can easily see the secure connection by seeing on the address bar there should be HTTP or HTTPS before the address by going on a specified address.
and the other way of security is the connection make your connection secure by encrypting the password.
Insulate personal or financial information with automation.
You can protect both your customer and your employees by using automated systems to handle personal financial information, for example, when taking payment from a customer. The human agent can pass the customer over to an automated Interactive Voice Response (IVR) system at the time payment card details are required. Once the card has been processed, the customer will then be returned to the agent. Automating the capture of financial or personal information ensures that the agent never hears or has access to this information.
Ensure you are PCI compliant.
The Payment Card Industry Data Security Standard applies to companies of any size that accept credit card payments. You need to plan how your IT system securely stores customer information, how you will protect that data from any security breach and how your firewall can allow secure remote access. The industry best-practice security standards fall into 12 major areas, providing a comprehensive security framework that should be your baseline.
Use multi-factor authentication or biometrics for access.
Multi-factor authentication (MFA) is commonly used to ensure that only authorized users can access a controlled system. The simple way to think about it is “something they know and something they have.” Users already “know” the something as — a username and password for most systems. A system with MFA will then prompt for information that needs to be retrieved from an additional device — “something they have” — such as a numeric key fob or other client device. The user can only login by correctly passing through both levels of authentication. Given the low cost today of biometric-scanning devices for fingerprints, palm prints or eyes (retina scans), it is also feasible to consider biometric tests in addition to passwords. Remote workers should never be able to access your system just because they know a username and password.
Lockdown the PC desktop.
Your remote workers will be using standard PC equipment connected to the Internet, but certain minimum standards such as an antivirus firewall will be required in addition to basic protection. All non-business functionality will need to be locked down and unavailable when the system is being used for your business. This means that functionality such as printing the screen or saving data to the hard drive must be disabled. Virtual Desktop Interface (VDI) applications are sophisticated tools that allow a secure environment to be created — by harnessing these tools and only allowing remote employees to access from a locked and controlled cloud system, you will ensure a more secure environment.
Encrypt those calls.
In everyday life, most people are already using end-to-end encryption when they send messages using apps such as WhatsApp or Skype. Any communication undertaken by your remote workers needs to utilize similar levels of encryption, so if their connection is hacked it will be impossible to make sense of the data transfer — only the sender and receiver will have the key to the encrypted communication stream.
Creating a culture of security by offering training to your remote team is also extremely important, because the team may spot attempted security breaches even before your security team does. This security-first culture, combined with the approach I have outlined in these simple measures, addresses the three most significant security challenges that any work-at-home model has to contend with:
  • The desktop: Controlling the desktop so that the agent has no opportunity to record any personal customer information
  • The network: Eliminating the chance of access to the system via a hacked network
  • Personal data: Payment shielding so detailed personal information is never shared — even if a rogue agent takes a job with the intention of stealing data, they will not have access to any personal payment information.
