Inthe part I will be taking about the security on Androids. One thing thesesecurity phones have in common is that they all run versions of google Androidoperation system. However, Building on Android is much easier than building asmart phone OS from scratch. Android have many features in a way to keep youphone safe such as the first one Google Play Protect. GooglePlay Protect help work to keep your device, date and App safe.

It scans yourdevice and is constantly improving to make sure that it is safe. One way thatis does this is that if you’ve misplaced your device, find my device have youcovered. One way that it does this is that you can locate your device bysigning into your google account, and even call it directly from the web. With safebrowsing protection in Chrome, you can browse with confidence. If you visit asite that’s acting out of line, you’ll be warned and taken back to safety. IsGoogle Play secure? The security system never sleeps. Google Play Protectcontinuously works to keep your device, data and apps safe. It actively scansyour device and it constantly improving to make sure you have the latest inmobile security.

Another part of the application is that Asurion hasimplemented measures to help protect against the unauthorized access, loss,misuse and alteration of the technical data and your P11. Asurion utilizessecurity measures and encryption technology to help protect the integrity ofthe Technical Data and your P11.Moveoverwhat is meant by protected apps is a feature in Cyanogen Mod and Cyanogen OSwhich hides selected apps from the main interface making them hard to beaccessed by an unauthorized person. With safe browsing protection in Chrome,you can browse with confidence. If you visit a site that’s acting out of line,you’ll be warned and taken back to safety. This is one of the features that ithas got to secure your phone. Google Play Protect, which scans all apps formalware before and after you install them, is automatically enable on yourdevice.

To see more about Play protect: open you device’s google Play storeapp. tap menu play protect icon.Android’srecently released Oreo update packs in plenty of features, including a batterylife boost and a notifications rethink. But Oreo’s most important improvementswill happen behind the scenes, with a host of security updates designed toevolve with ever-expanding digital threats.

From halting ransomware to blockingmalicious apps and easing Android’s longstanding fragmentation woes, Oreotackles some big problems. For the security developers who work behind thescenes, though, it’s just one more step on a journey that never really ends.With more than two billion monthly active devices, the majority of them not onthe latest or even recent version, Android presents a popular target forhackers. Stopping them takes more than a yearly release. It takes the kind oflong view, holistic effort that Google has employed for years.

For the security developers who work behind thescenes, though, it’s just one more step on a journey that never really ends.With more than two billion monthly active devices, the majority of them not onthe latest or even recent version, Android presents a popular target forhackers. Stopping them takes more than a yearly release. It takes the kind oflong view, holistic effort that Google has employed for years.TakeGoogle Play Protect, part of Android Security’s detection and reactioninfrastructure, which scans devices for suspicious app activity.

With 50billion apps scanned per day, precision counts. The app scanning that goes intoPlay Protect has existed behind the scenes under other names for years, butAndroid Security surfaced the mechanism for customers this year and has used itto do a new type of visibility research. Android data scientist Megan Ruthvenand others have developed techniques for detecting distribution of extremelytargeted malware, the type that might be narrowly distributed to high-valuemarks. So far, Ruthven’s research has turned up 3,000 unique samples ofmalware, each with an average of just 130 users affected. This ability todetect such a faint signal helps protect each individual user, while alsoallowing Android Security to spot nascent threats early. Android’s scannersdon’t catch everything, though, and researchers still regularly find malicioussoftware that has made it past Google’s protections to land in the Play Store. InAugust alone, third-party analysts discovered hundreds of compromised financialapps, spyware, and even apps that spread malware to build Android botnets andpower DDoS (distributed denial of service attacks).

DDoS attacks are when aflood of incoming packets come through the network and overload the systemcausing it to slow down or crash. Despite those recent fumbles, the dangers ofdownloading apps from third-party app stores far exceed those posed bymainstream apps in Google Play. So Android Security implemented small butsignificant changes in Oreo, aimed at regularly reminding users about whattypes of apps they’re downloading. For example, in previous versions of Androida user could enable downloads from outside of Google Play through a settingcalled Unknown Sources. Beginning with Oreo, users now receive a prompt toconfirm that they want to download any Unknown Source app before doing so, as amore salient reminder to proceed with caution. Android Security also takes abroad view.

When tracking emerging attacks, the team doesn’t just rely onAndroid-specific data they also survey the general web to trace malwarefamilies and monitor malicious infrastructure. Inthe case of mobile ransomware, a small but growing type of attack, Androidalready had some defence advantages because it silos every app into a sandbox,rather than letting them all run together in an open environment. As a result,Android can contain malicious activity more effectively than a more open platformlike Windows. While tracking 30 families of Android ransomware, the teamdiscovered versions that exploited flaws to block users from accessing theirphone at the lock screen, through visual overlays, and by encrypting some data.Oreo adds reinforcements to Android’s sandboxing to plug many of these holes.The team also says that to this point it has still never seen ransomware thatcan render an Android device completely unusable.

Android Security has alreadyworked to bring a number of big device makers on to a monthly update schedule,which has helped improve fragmentation a bit. The effort has a number oflimitations, though; only a few dozen models end up getting regular updates. SoOreo is working to address the tension head-on with a new feature calledProject Treble. Make Android easier to update regardless of device and carrier,by segmenting Android’s code into portions that interact with vendor-specificattributes and portions that deal with the more general, platform-agnosticoperating system. Ideally, that makes it possible to push software updates tothe core Android component of every device without dealing with vendor-specificincompatibilities. Manufacturers could also ship updates for their tailoredportions of the code. Though many security features are conceptually broad toprotect against a variety of both present and future unknown threats, AndroidSecurity developers note that they have some additional foresight into whereattackers will focus simply because they know where they have already bolsteredtheir defences and made attacks impractical. Inpractice, here’s how that plays out: In 2014 only about 4 percent of Androidbugs targeted the kernel (the central coordinator of an operating system).

By2016 the number was up to 44 percent, because security enhancements had cut offeasier routes for attackers. TheAndroid Security team can’t be sure of what attacks will spike in the future,and Oreo will give them a leg up regardless. But whatever is up next, the teamwon’t be waiting until the big 2018 Android release to combat it. Ina mobile security, a sandbox is a security mechanism for separating runningprograms, usually in an effort to mitigate system failures or softwarevulnerabilities from spreading. It is often used to execute untested oruntrusted programs or code, possibly from unverified or untrusted thirdparties, suppliers, users or websites, without risking harm to the host machineor operating system.

A sandbox typically provides a tightly controlled set ofresources for guest programs to run in, such as scratch space on disk andmemory. Network access, the ability to inspect the host system or read frominput devices are usually disallowed or heavily restricted.Inthe sense of providing a highly controlled environment, sandboxes may be seenas a specific example of virtualization. Sandboxing is frequently used to testunverified programs that may contain a virus or other malicious code, withoutallowing the software to harm the host deviceAndroid hasbuilt-in security features that significantly reduce the frequency and impactof application security issues. The system is designed so that you cantypically build your apps with the default system and file permissions andavoid difficult decisions about security.

Thefollowing core security features help you build secure apps:TheAndroid Application Sandbox, which isolates your app data and code executionfrom other apps. An application framework with robust implementations of commonsecurity functionality such as cryptography, permissions, and secure IPC.Technologies like ASLR, NX, ProPolice, safe_iop, OpenBSD dlmalloc, OpenBSDcalloc, and Linux mmap_min_addr to mitigate risks associated with common memorymanagement errors. An encrypted file system that can be enabled to protect dataon lost or stolen devices. User-granted permissions to restrict access tosystem features and user data. Application-defined permissions to controlapplication data on a per-app basis.

It is important that you be familiar withthe Android security best practices in this document. Following these practicesas general coding habits reduces the likelihood of inadvertently introducingsecurity issues that adversely affect your users.Ina Java programming language and development environment, the sandbox is theprogram area and set of rules that programmers need to use when creating Javacode called an applet that is sent as part of a page. Since a Java applet issent automatically as part of the page and can be executed as soon as itarrives, the applet can easily do harm, either accidentally or as the result ofmalicious intent, if it is allowed unlimited access to memory and operatingsystem services. The sandbox restrictions provide strict limitations on whatsystem resources the applet can request or access. The sandbox is implementednot only by requiring programmers to conform to certain rules but also byproviding code checkers.

The Javalanguage itself provides features such as automatic memory management, garbagecollection, and the checking of address ranges in strings and arrays thatinherently help to guarantee safe code. In addition, Java includes a compiledcode Java’s compiled code is known as bytecode verifier that guaranteesadherence to certain limitations. Java also provides for a local name spacewithin which code may be restricted. The Java virtual machine the layer thatinterprets the Java bytecode for a given computer platform also mediates accessto system resources and ensures that sandbox code is restricted. To concludethese security features are there to make safe your Android phone by doing allthe things that’s mentioned in the above and android try to make it easier forthe end user to go though there day to day life.
