Inner ring security system

It is surveillance camera system, fire alarm and gas leak alarm. The sensors are also often installed in the garage or kitchen. The fire alarm will sound continuously for 5 minutes as soon as the fire occurs and. Warning system immediately sends a message to the landlord. If after 5 minutes there is no fire alarm breaker, the system will automatically disconnect the whole house to avoid spreading fire.

Overview of surveillance security systems (Part 1)

Currently, security protection systems are the smart solution to ensure safety for buildings. They are increasingly modernized to meet the needs of users. Find out an overview of this system in the following article.

Why is surveillance security systems becoming more and more important?

Security system is an indispensable important factor for every construction project. For example, houses, apartments, buildings, shopping malls, businesses, schools … It is like a bodyguard that can protect these buildings 24/24 against the potential unsafe risks. hidden. Modern technology has given birth to security systems with multiple protection rings. These include access control systems, CCTV systems and alarm systems.

The use of surveillance security systems in construction works will contribute to maximum safety for people living in that construction.

The components of surveillance security system 

Access control system

The function of this system is to completely control the distribution and circulation of groups of people. This system includes surveillance cameras. They will record images of vehicles entering and leaving the building. Next to that are magnetic card swipe machines for parking. So this system is present in parking lots, basements of buildings, shopping centers or supermarkets.

CCTV system

Cameras are installed in all key areas. For example, gates, lobbies, corridors, fences … Currently CCTV is equipped with high technology. They are capable of meeting the safety needs of the user.

Surveillance cameras can record images to be monitored inside and outside. Then the image (video clip) is transmitted to the supervisor. This process takes place through devices such as computers and smartphones connected to the Internet. Thereby the supervisor can manage the operation of the project actively and more conveniently.

The advantages of surveillance cameras today

On the market today, CCTV are manufactured by modern technology. So images will have high resolution, clear (full HD or higher). Thanks to the application of transmission solutions as well as HD signal distribution, the cameras ensure that images are transmitted with constant quality. CCTV system ensures 24/24 operation even during power failure.

Three security ways to protect your home network

Internet users can set their own security mode to protect their home network and avoid network attacks.


The router is the first security barrier when accessing the network. Anyone who wants to connect to the internet is done through a router such as a hardware device, wired or wireless (Wi-Fi), which allows users to communicate between a local area network like a computer and other devices are connected to another internet.

Following the advice of experts, setting the highest security level on a router is a way to keep computers, printers, and data safe from network attacks.

Set a password

To set security, the password on the user’s router must not match the default password information on the network. There are two types of routers on the market, with secure and non-secure configurations. If a router is not secure, allowing it to connect to it without requiring any administrative password or using the default password, then anyone can connect to the router and access the user’s local network. A hacker can change passwords, track victims, or even access files on network drives.

1

According to experts, the router should be secured with a different administrator password, not a password set by the manufacturer.

Always update the firmware

Many router manufacturers roll out software updates throughout the year to address security issues. Therefore, a router with the latest updates will be less likely to be infected with malware.

Most router vendors apply automatic updates to firmware without requiring customers to perform this operation. New-generation router models also offer a mobile application that can be downloaded to the phone like any other application and used to check for updates.

However, if the firmware update is not done automatically, users should visit the router manufacturer’s website. The next step is to go to Support and identify the exact update based on the router’s specific name and ID (usually found on the router itself).

Use virtual private networks (VPNs)

Beyond the hardware security inside a network, a virtual private network (VPN) is a server that users connect to reroute external internet activities. A VPN can protect your identity and user information by providing a way to browse the web privately (but not always anonymously), A VPN is popular from different reasons, Online Casino players for example often use VPN to keep their account more secured or if they need to log in to another country to play different online casino games.

Theoretically, all traffic flowing through a VPN connection is safe and cannot be intercepted or recorded by anyone else, suitable for use on both local and public networks.

Network security has been simplified and enhanced by many modern router settings. However, manufacturers often do not turn on, so users are convenient in the initial setup. Activating the highest level of security on the router is the key to protect computers, printers, and data from attacks over the network.

Technology experts advise users to be awake to be secure from start-up to shutdown.

The White House Released National Strategy to Secure 5G of the United States

The White House’s strategy focuses on four lines of effort and guidance on how the US government approaches 5G for the near future.

This week, the White House released its National Strategy to secure 5G of the US to formally frame how the country will safeguard 5G wireless infrastructure at home and abroad.

The policy document sets forth the US president Donald Trump’s vision for the nation to lead the development, management, and deployment of secure 5G communications infrastructure all over the world, arm-in-arm with the closest partners and allies.

The White House’s release marks its president’s initial move in order to meet the requirements that were listed in the Secure 5G and Beyond Act, which he also signed on Monday. It directs the president to produce a strategy with the aim of ensuring the security of the next wireless infrastructure and systems within its 180-day enactment.

The document outlines four lines of effort which the bill called for it to include. Each of them briefly lays out the approaches and aims of the administration to facilitate the domestic rollout of 5G; identify the core security principles and assess the risks of 5G infrastructure; assess the risks to US economic and national security during worldwide development of 5G infrastructure, and promote global development and deployment of 5G.

A senior administration official reiterated Wednesday that the publication fulfills one of the key obligations of the administration under the new bill, meaning to complement the Secure and Trusted Communications Networks Act, which has also been signed into law recently by Trump.

5G technology is anticipated to unleash the levels of connectivity between millions of internet devices and there have already been a variety of deployments that have made their way across the U.S. as well as in some federal agencies. However, the release of this strategy comes when the US is also reconciling potential threats from China and other countries that might lurk in its telecommunications and 5G supply chain.

Pakistan offers Qatar security for the 2022 FIFA World Cup

Pakistan President Arif Alvi offered Qatar of providing security for the 2022 FIFA World Cup that is planned to take place in the Gulf country, emphasizing that the country had a variety of experience in that field.

Meeting with Commander of the Qatar Emiri Guard, Maj-Gen Hazzaa Bin Khalil Bin Mansour Al-Shahwani, who called on him in Islamabad with a delegation, Dr. Alvi said that there is a lot of scopes existed between the two countries, including defense export and joint production ventures.

According to Radio Pakistan, the president underscored that having a lot of experience in the field of security, as well as the professionalism of Pakistan’s armed forces, make his country be able to provide Qatar security for the next FIFA World Cup.

He stressed the need for enhancing the training cooperation and professional interaction between the defense forces of the two countries and highly appreciated the agreement for the sale of 8 Super Mushak aircraft worth $57.74 million to Qatar in 2016.

Dr. Alvi also urged Qatar to support Pakistan in its endeavors in order to highlight Indian human rights violations in Kashmir before the world. He emphasized the need for the worldwide community to persuade India to resolve the Kashmir dispute in accordance with the United Nations Security Council resolutions.

“The fascist Indian regime is flagrantly violating the human rights of Kashmiris by revoking the special status of occupied Kashmir and by suspending their civil liberties. The Indian government has adopted a hostile attitude towards all its minorities,” the report quoted Dr. Alvi as saying.

Maj-Gen Al-Shahwani said that Qatar considered supporting Pakistan at all levels as a religious duty.

Meeting with army chief

Meanwhile, the Qatari commander called on army chief General Qamar Bajwa at the General Headquarters (GHQ) in Rawalpindi.

Matters of the regional security situation and mutual and professional interest were discussed in the meeting.

The visiting dignitary highly appreciated the professionalism of the Pakistan Army and showed his desire for increased Pakistan-Qatar defense collaboration.

Google Creates Powerful New Security System for Enterprises (part 2)

Operational flexibility

To achieve OpenSK aims, Google is using the Rust programing language developed by rival browser publisher Mozilla to code the key’s OS.

Named TockOS, its features include an architecture fencing the safety applet from its drivers as well as from the kernel within the 32-bit Arm core of Nordic SoC.

Google’s engineers say the programing language works to limit logic attacks because of the straightforward abstraction and safety enhancements for its flash-friendly memory. TockOS is out there on the GitHub code repository, where developers can access blueprints and upload innovations.

Tighter measures

Two-factor authentication is a minimum of as old because the cash machine, which needs a card and pre-set password to access an account. With the arrival of online banking, the methodology has produced innovations like one-time codes sent via SMS services to execute instructions.

But the safety vulnerabilities of wireless transmitters make them but ideal – hence, Google’s action to prop up defenses. Other moves by the corporate include barring users from accessing G Suite productivity tools via apps that share usernames and passwords.

Google is also blocking downloads by its Chrome browser of mixed-content files containing text and pictures over unencrypted web protocols.

Cloud challenges

Making security an indicator is increasingly important for Google because it leverages its dominance in search to other sectors. Quite two billion people use its Gmail platform to send e-mails over the online and quite one billion computing devices run its Chrome browser.

Yet, it’s within the cloud where Google lags, trailing Amazon Web Services and Microsoft Azure by a good margin in global league tables. Both competitors support the FIDO Alliance push for an internet that’s password-free.

In the same time, the Alphabet subsidiary is setting up partnerships driving enterprises to its Google Cloud Platform when they revamp their IT landscapes. Taking up the open-source security baton is another way for Google to stick it to the market leaders.

Google Creates Powerful New Security System for Enterprises (part 1)

The Silicon Valley giant is using open-source encryption to form the web a safer place. By offering developers first crack at cutting their own pass keys, Google hopes that increased adoption of its new security system will lure the Fortune 500 to its cloud services.

The search-and-advertising company’s OpenSK project offers a more robust layer of protection than passwords, which are soft targets for attackers seeking ways into personal accounts. Once there, they will invade systems and compromise companies.

OpenSK uses a two-factor authentication standard pioneered by the Fast Identification On-Line Alliance, or FIDO, which calls on hardware containing unique access codes instead of passwords. The industry group is committed to a password-free internet.

Making software libraries publicly available to run reference hardware provides developers with tools to make their own FIDO authenticators. Google engineers call OpenSK an experimental research platform but the corporate hopes that enterprises will examine the technology then adopt it.

FIDO-friendly firmware

To spur development, Google has added a dongle produced by Nordic Semiconductor to the Titan family of security keys it introduced two years ago. The Norwegian maker’s widget contains a system-on-chip that interfaces through a USB port or using Bluetooth wireless and near-field communication.

The Nordic dongle and tokens within the Titan lineup contain firmware compatible with FIDO U2F and FIDO2 standards for both desktop and mobile. They use authentication protocols from the seven-year-old alliance taking passwords out of the equation.

The result’s a design that Google says can beat the bots, phishing scams and targeted attacks that employ public-key cryptography to verify user identities and log-in pages – albeit account holders inadvertently display passwords.

Indeed, Google claims it hasn’t suffered a breach since shifting its quite 80,000 employees to Titan in 2017. The Nordic dongle possess an equivalent capabilities and lets users fashion their own carrying case with a 3D printer.
