Which of the following is considered a secure protocol?
Secure Sockets Layer (SSL) Protocol Overview
|Application Layer||HTTP, NNTP, Telnet, FTP, etc.|
|Secure Sockets Layer||SSL|
Which type of hypervisor is installed on bare metal?
A bare metal hypervisor or a Type 1 hypervisor, is virtualization software that is installed on hardware directly. At its core, the hypervisor is the host or operating system. It is structured to allow for the virtualization of underlying hardware components to function as if they have direct access to the hardware.
What temperature is considered to be ideal for a server room?
According to OpenXtra, server room temperatures should not dip below 50 degrees Fahrenheit, and should not exceed 82 degrees Fahrenheit. The optimal temperature range is between 68 and 71 degrees Fahrenheit.
What software emulates the hardware on which an operating system runs?
The software layer that emulates the necessary hardware for an operating system to run in. It is the hardware virtualization that lets multiple operating systems run simultaneously on a single computer, such as a network server.
What does anti virus software do?
Antivirus software, or anti-virus software (abbreviated to AV software), also known as anti-malware, is a computer program used to prevent, detect, and remove malware. Antivirus software was originally developed to detect and remove computer viruses, hence the name.
Which type of protocol allows for a secure data transmission using encryption methods?
Web-based secure transmission. Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), are cryptographic protocols that provide secure communications on the Internet for such things as web browsing, e-mail, Internet faxing, instant messaging and other data transfers.
Is KVM a Type 1 or Type 2 hypervisor?
KVM converts Linux into a Type-1 hypervisor. Xen folks attack KVM, saying it’s like VMware Server (the free one that was called “GSX”) or Microsoft Virtual Server because it’s really a Type 2 hypervisor that runs on top of another OS, rather than a “real” Type 1 hypervisor.
What is the difference between Type 1 and Type 2 hypervisor?
The main difference between Type 1 and Type 2 hypervisors is that Type 1 runs on bare metal and Type 2 runs on top of an OS. The physical hardware that a hypervisor runs on is typically referred to as a host machine, whereas the VMs the hypervisor creates and supports are collectively called guest machines.
What is Type 2 hypervisor?
A Type 2 hypervisor, also called a hosted hypervisor, is a virtual machine manager that is installed as a software application on an existing operating system (OS). There are two types of hypervisors: Type 1 and Type 2.
At what temperature do servers fail?
“Studies by Intel and Microsoft showed that most servers do fine with higher temperatures and outside air, easing fears about higher hardware failure rates. Dell recently said it would warranty its servers to operate in environments as warm as 45 degrees C (115 degrees F).”
Can humidity damage electronics?
If a device is moved from a cool environment to one that is warm and humid, circuit boards may become coated in moisture. Also important is protecting electronics from low humidity environments, which can lead to static electricity discharge that results in irreversible damage to components.
How big should a server room be?
Physical Space and Temperature Requirements. Ceilings should be at least 9 feet high. Server room doors need to be between 42 and 48 inches wide, and at least 8 feet tall. Enough room for future growth, including space for extra cooling units.
What are the different hypervisors?
There are two types of hypervisors:
- Type 1 hypervisor: hypervisors run directly on the system hardware – A “bare metal” embedded hypervisor,
- Type 2 hypervisor: hypervisors run on a host operating system that provides virtualization services, such as I/O device support and memory management.
What is server virtualization?
Server virtualization is the masking of server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users. The server administrator uses a software application to divide one physical server into multiple isolated virtual environments.
What type of malware replicates through networks?
Two of the most common types of malware are viruses and worms. These types of programs are able to self-replicate and can spread copies of themselves, which might even be modified copies. To be classified as a virus or worm, malware must have the ability to propagate.
What is best anti virus software?
Kaspersky Anti-Virus earned perfect scores in all the latest independent lab tests, and Bitdefender Antivirus Plus came very close. A single subscription for McAfee AntiVirus Plus lets you install protection on all of your Windows, Android, Mac OS, and iOS devices.
What does a hacker do?
Computer hackers are unauthorized users who break into computer systems in order to steal, change or destroy information, often by installing dangerous malware without your knowledge or consent. Their clever tactics and detailed technical knowledge help them access the information you really don’t want them to have.
What programs are most likely affected by macro viruses?
A macro virus most typically affects word editing programs. An example of this would be Microsoft Word. They usually attack products that are related to the actual operating system. More than 80% of all computer viruses are caused by a macro virus.
Does https encrypt data in transit?
Data can be exposed to risks both in transit and at rest and requires protection in both states. For protecting data in transit, enterprises often choose to encrypt sensitive data prior to moving and/or use encrypted connections (HTTPS, SSL, TLS, FTPS, etc) to protect the contents of data in transit.
Which cryptographic protocols can be used by SSL TLS?
SSL and TLS are commonly used by web browsers to protect connections between web applications and web servers. Many other TCP-based protocols use TLS/SSL as well, including email (SMTP/POP3), instant messaging (XMPP), FTP, VoIP, VPN, and others.
What is encrypt data at rest?
Encryption. Data encryption, which prevents data visibility in the event of its unauthorized access or theft, is commonly used to protect data in motion and increasingly promoted for protecting data at rest.
What hypervisor does AWS use?
AWS’s FAQ about the new instances notes “C5 instances use a new EC2 hypervisor that is based on core KVM technology.” That’s explosive news, because AWS has long-championed the Xen hypervisor. The Xen Project has drawn strength from the fact the mightiest public cloud uses its open-source wares.
Is VMware a Type 1 or Type 2 hypervisor?
Type 1 hypervisors are commonly considered bare metal hypervisors, in that the hypervisor code itself runs directly on top of your hardware. VMware Workstation is an example of a type 2 hypervisor. You can install it on top of an existing instance of Windows (and a number of Linux distributions).
Is Docker a hypervisor?
Well that’s the main advantage of using docker container virtualization. So this type of virtualization is basically operating system agnostic. In other words, you can have a hypervisor running on a windows system create a virtual hardware and can have Linux installed on that virtual hardware, and vice versa.
