POE camera systems are made up of a single IP cabling network that consists of many cameras. These systems don’t use any additional cables or connectors, but just one common cable. This allows for optimal clarity, and data transmission over a single cable, but it has the drawback of requiring much more room than a normal security system. So it is useful for many applications, where the space to place the cameras is limited, but not ideal for a large installation.

These days there are many POE Camera devices in the market, which makes finding a good one a task in itself.

What are the benefits of a POE camera, and why are they so popular?

Single IP network

It is important for people who want to do their own surveillance and recording to be able to do so, from anywhere. There are several different models available, but the benefits of a single IP network are the most important feature. For instance, when one is using this type of security camera, then the signal is sent over the same data transmission over which the cameras themselves communicate. This is very important for data transmission over VoIP networks and makes it easy for the system administrator to monitor what is going on.

Analog video resolution

Another great aspect of this type of security camera system is that they have a number of features that make them very efficient. For example, they will usually have an analog video resolution that makes it easy for them to record high-quality video. This ensures that all the images seen through the lenses are clear and of a high resolution. There are a number of other features available on some models, but the majority of them will have a normal analog video resolution unless specified otherwise.

A few of the other features that are important include:

Fast process with Digital video resolution

Some POE cameras will also have a digital video resolution for use with digital photography equipment. There is no reason why a person wanting to use the system with a digital camera should miss out on the advantages that this type of camera has to offer. Digital video is capable of offering excellent image resolution and can also be transmitted directly to a host computer. The transfer of the video is very fast, meaning that the operator does not need to wait for the upload to finish, as it normally would in the case of analog security cameras that have to use a physical cable for the data transfer process. This means that the process can be done even when the cameras are being used in the field.

Built-in DVR

Other features include such as a built-in DVR. This is a great feature for people who want to keep a record of all the activities taking place, but who don’t want to spend the money on a digital camera. It is also useful for controlling the video and audio from remote locations, which is useful for businesses where the employees do a lot of work from their laptops.

VoIP function

Some of these POE cameras even have a dedicated VoIP function, which is useful for making voice calls over the Internet instead of using public phone lines.

Things to consider when buying a POE camera

It is worth thinking carefully about what features a person should consider when buying a security system with a POE camera.

· If all they are looking for is a basic set of features, it might be worth setting up a DIY home security system. These types of cameras are a great alternative to more expensive surveillance cameras that use electricity. These devices can also save people money since they don’t need to pay for a power source.

· Some people even choose to put their POE surveillance cameras in monitored CCTV security systems, in order to keep an eye on employees who aren’t actually on duty.

· When setting up a POE camera system in an area where electricity is available, it’s always a good idea to make sure there’s a good power source close by.

· It’s important to always protect the most vulnerable POE routers with one of the most powerful and robust wireless security cameras on the market, in order to ensure that no one can disable or destroy them.

Everything around us has become smart, like smart infrastructures, smart cities, autonomous vehicles, to name a few. The innovation of smart devices makes it possible to achieve these heights in science and technology. But, data is vulnerable, there is a risk of attack by cybercriminals. To get started, let’s know about IoT devices.

What are IoT devices?

The Internet Of Things(IoT) is a system that interrelates computer devices like sensors, software, and actuators, digital machines, etc. They are linked together with particular objects that work through the internet and transfer data over devices without humans interference.

Famous examples are Amazon Alexa, Apple SIRI, Interconnected baby monitors, video doorbells, and smart thermostats.

How could your IoT devices be vulnerable?

When technologies grow and evolve, risks are also on the high stakes. Ransomware attacks are on the continuous increase; securing data has become the top priority.

When you think your smart home won’t fudge a thing against cybercriminals, you should also know that they are vulnerable. When cybercriminals access our smart voice speakers like Amazon Alexa or Apple Siri, it becomes easy for them to steal your data.

Cybersecurity report 2020 says popular hacking forums expose 770 million email addresses and 21 million unique passwords, 620 million accounts have been compromised from 16 hacked websites.

The attacks are likely to increase every year. To help you secure your data of IoT devices, here are some best tips you can implement.

Tips to secure your IoT devices

1. Change Default Router Name

Your router has the default name of make and model. When we stick with the manufacturer name, attackers can quickly identify our make and model. So give the router name different from your addresses, without giving away personal information.

2. Know your connected network and connected devices

If your devices are connected to the internet, these connections are vulnerable to cyber attacks when your devices don’t have the proper security. Almost every web interface is equipped with multiple devices, so it’s hard to track the device. But, it’s crucial to stay aware of them.

3. Change default usernames and passwords

When we use the default usernames and passwords, it is attackable. Because the cybercriminals possibly know the default passwords come with IoT devices. So use strong passwords to access our IoT devices.

4. Manage strong, Unique passwords for your IoT devices and accounts

Use strong or unique passwords that are easily assumed, such as ‘123456’ or ‘password1234’ to protect your accounts. Give strong and complex passwords formed by combinations of alphabets, numeric, and not easily bypassed symbols.

Also, change passwords for multiple accounts and change them regularly to avoid attacks. We can also set several attempts to wrong passwords to set locking the account to safeguard from the hackers.

5. Do not use Public WI-FI Networks

Are you try to keep an eye on your IoT devices through your mobile devices in different locations. I recommend you not to use the public WI-FI network to access them. Because they are easily accessible through for everyone, you are still in a hurry to access, use VPN that gives them protection against cyber-attacks, giving them privacy and security features, for example, using Express VPN.

6. Establish firewalls to discover the vulnerabilities

There are software and firewalls like intrusion detection system/intrusion prevention system in the market. This will be useful to screen and analyze the wire traffic of a network. You can identify the security weakness by the firewall scanners within the network structure. Use these firewalls to get rid of unwanted security issues and vulnerabilities.

7. Reconfigure your device settings

Every smart device comes with the insecure default settings, and sometimes we are not able to change these default settings configurations. These conditions need to be assessed and need to reconfigure the default settings.

8. Authenticate the IoT applications

Nowadays, every smart app offers authentication to secure the accounts. There are many types of authentication methods like single-factor authentication, two-step authentication, and multi-factor authentication. Use any one of these to send a one time password (OTP) to verify the user who logs in the smart device to keep our accounts from falling into the wrong hands.

9. Update the device software up to date

Every smart device manufacturer releases updates to fix bugs in their software. These security patches help us to improve our protection of the device. Also, update the software on the smartphone, which we are used to monitoring the IoT devices to avoid vulnerabilities.

10. Track the smartphones and keep them safe

When we connect the smart home to the smartphone and control them via smartphone, you need to keep them safe. If you miss the phone almost, every personal information is at risk to the cybercriminals. But sometimes it happens by accident, makes sure that you can clear all the data remotely.

However, securing smart devices is essential in the world of data. There are still cybercriminals bypassing the securities. So make sure to do the safety measures to avoid our accounts falling out into the wrong hands. I hope these steps will help you all to secure your IoT devices.

Lax Security Exposes Smart-Irrigation Systems to Attack Across the Globe

More than 100 smart-irrigation systems deployed across the globe were installed without changing the factory’s default, passwordless setting, leaving them vulnerable to malicious attacks, according to recent findings from Israeli security research firm Security Joes.

The researchers immediately alerted CERT Israel, the affected companies and the irrigation system vendor, Mottech Water Management, which did not immediately respond to a request for comment from Threatpost.

Mottech’s system allows for real-time control and monitoring of irrigation for both agricultural and turf/landscaping installations, via desktop and mobile phone. Sensor networks allow for the flexible and real-time allocation of water and fertilizer to different valves in the system. Access to the network could result in an attacker being able to flood fields or over-deliver fertilizer, for instance.

Security Joes regularly scans for Israeli open devices on the internet to check for vulnerabilities, the firm’s co-founder Ido Naor told Threatpost. Recently, its researchers discovered that 55 irrigation systems within Israel were visible on the open internet without password protections. After expanding their search, they found 50 others scattered around the world in countries including France, South Korea, Switzerland and the U.S.

“We’re talking about full-fledged irrigation systems, they could be entire cities,” Naor said. “We don’t look closely at what’s behind the address, because we don’t want to cause any trouble.”

Naor said that at last check, only about 20 percent of the identified vulnerable irrigation devices have had mitigation efforts taken to protect them so far.

Israel’s Water Systems Under Attack

There’s good reason for alarm about water systems not being secured, particularly in Israel. Just last April, a cyberattack on Israeli water systems, reportedly launched by Iran, attempted to increase the mix of chlorine in the water to poison the civilian population and ultimately interrupt the population’s water supply, The Times of Israel reported.

Yigal Unna, the head of the country’s National Cyber Directorate addressed the CybertechLive Asia conference in late May with the ominous warning that the direct cyberattack on people represented a new chapter in cyberwarfare, according to The Times of Israel.

“Cyber-winter is coming and coming even faster than I suspected,” he told the conference, according to the report. “We are just seeing the beginning.”

Unna was correct. Just weeks later in July, the Israeli Water Authority said that it was able to stop an attack on agricultural water pumps in Galilee, and another on water-supply infrastructure in the “center of the country,” reports.

The irrigation systems which were discovered without password protection aren’t related to the previous attacks, Naor said.

Locking Down Utilities Beyond Israel

These types of vulnerabilities certainly aren’t limited to Israel.

Last month, six critical flaws in CodeMeter, software used to power industrial systems in the U.S., including water and electric utilities, were discovered which could be exploited to launch attacks or even allow third-party takeovers of systems.

Over the summer, researchers found that VPNs used for remote access to operational technology (OT) networks in industrial environments left field devices open to attacks, which could cause shutdowns or even physical damage.

Governments are making attempts to keep up with the proliferation of internet-of-things (IoT) devices throughout critical-infrastructure systems. In the U.S., the House of Representatives passed legislation in September establishing minimum requirements for IoT devices within the federal government.

“Most experts expect tens of billions of devices operating on our networks within the next several years as the [IoT] landscape continues to expand,” the legislation’s so-sponsor Senator Cory Gardner (R-Co.) said in a press release. “We need to make sure these devices are secure from malicious cyberattacks as they continue to transform our society and add countless new entry points into our networks, particularly when they are integrated into the federal government’s networks.”

System Databases in SQL Server

Introduction

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

• Master
• Model
• MSDB
• Tempdb
• Resource

Master

• This database contains all the System level Information in SQL Server. The Information in form of Meta data.
• Because of this master database, we are able to access the SQL Server (On premise SQL Server)

Model

• This database is used as a template for new databases.
• Whenever a new database is created, initially a copy of model database is what created as new database.

MSDB

• This database is where a service called SQL Server Agent stores its data.
• SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.

TempDB

• The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
• User can create their own version of temporary tables and those are stored in Tempdb.
• But this database is destroyed and recreated every time when we restart the instance of SQL Server.

Resource

• The resource database is a hidden, read only database that holds the definitions of all system objects.
• When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.
