What is Java?
- JavaScript is a programming language that allows Web pages to be dynamic. Without JavaScript, the Web would consist of mainly boring text instead of interactive buttons, sliders, and fancy website integrations.

- When you install Java on your Mac, you’re installing the Java Runtime Environment, which is relatively secure and a place to run Java-based applications on their own, though it’s not used often. The problem is the included Java Browser plug-in, which enables Java content to run inside any browser on your system.

The Hole in Your Mac’s Security
- This article is good, but has some inaccuracies and bias.
The most obvious claims are that most people don't need Java, that Java does not perform any checks on the software it runs, and the very obvious contradiction of 'Stupidly, Java also doesn’t update itself' followed later by 'Java automatically checks for updates.'Java was the first mainstream programming environment to implement the sandbox model of application execution, preventing applications from performing any action outside of the sandbox (aka. virtual machine). When Java applications are written and run properly you do not need to disable this sandboxing. The Australian government clearly violated best practices in having an unsigned application that needs the ability to write to disk, thus requiring the running of Java in an 'unsafe mode.' The new OS model of only running 'signed' applications was actually brought to the mainstream by Java in the 1990's, with jar signing and sandboxing. Besides these obvious misrepresentations of Java, many applications utilize Java, without the user even being aware. It is the exclusion of Java from the OS that has led to each of these applications installing its own version of Java within the application. A perfect example of this is Minecraft, which was written in Java, and ported to .Net after its acquisition by Microsoft. Most parents have this installed and don't even know that it contains the Java Runtime.To be fair and unbiased, ALL applications have vulnerabilities and Macs are only safer than Windows and Linux/BSD because the user base is relatively low when compared to these other platforms. The following applications and platforms all have had at least as many security issues as Java, in most case far more, as Java performs extensive bytecode validation before running an application, looking for invalid sequences or known attack vectors, and can easily run applications within a sandbox.Adobe's Acrobat Reader, Flash, and Shockwave,
Microsoft's .Net, Word, Outlook, and the rest of the office suite,
Open Office, Libre Office, Internet Explorer, Google Chrome, the Safari browser, and any and all means of file/information sharing (torrents, file shares,SSH, web servers, FTP servers, MySQL, all database for that matter, and the list goes on and on) are all vulnerable to exploitation, Zero day or otherwise. This includes all versions of OS X, Windows, and Linux. All software is vulnerable, period. Safe browsing and computer usage should always be executed at all times, not just singling out one of many platforms/applications. Google Chrome's support of Java was terminated when Google stopped supporting the NSAPI, in favor for their browser plugin API. It was not specifically targeted at Java, but the media hyped it as targeted at Java.2 very clear examples of vulnerabilities that impacted almost all browsers and OS's were the JPEG and PNG exploits of years past. These vulnerabilities allowed malicious code to bypass the browser and image viewing application using malformed images that trick the computer into executing the malicious code contained within the image. These vulnerabilities were primarily because of the open source/reference implementations written in C/C++ that were vulnerable.My point is that just simply uninstalling Java or targeting Java will not secure your system. No one should be using Java Applets or Active X anymore, but the Java Runtime is more secure than most Objective C and C/C++ applications, due in large part to its open public source code review process and security being one of Java's primary design goals. Java is has proven over time to be more secure that Microsoft .Net and Javascript. Javascript, when running in an unsafe mode (allowing the 'eval' operation) is far less secure than any browser plugin.
Java's largest failing actually being that the automatic updates of the Java runtime has been hampered or disabled by some OS upgrades, which is Apple's fault, not Oracle's or Java's.If you want to secure your system, you must disable the Java browser plugin, Flash, Shockwave, and most importantly Javascript, on Windows you must also disable Active X. - Sorry for this late comment; I've just read this great article from Ben. I just have to say this, and it really only affects Australians.As a business owner with what's called an Australian Business Number (ABN), I am required to submit a Business Activity Statement (BAS) each quarter. To do that, I have to logon to the Business Portal, but there is a critical step that must be done - authentication using AUSkey, another form of digital ID.
BUT, guess what? Before any of that happens, Java has to be installed!And just to make Java run properly I have to select 'run in unsafe mode' in Safari Preferences.So, the ATO requires me to install a vulnerable system on my mac before I can proceed with my civic duty.
Crazy? - I never really what a terrible piece of software I had on my Mac.I just tried to update it as recommended, and it told me it was downloading the update, then that it was extracting the update, then the little window closed and I was back where I started!Sorry Java, you are the weakest link - goodbye!
- These commands will remove just the browser plugin and the preferences panel, it will leave the Java runtime in your system.
- Another great how-to article. But why fill it with other lies that take away from it's awesomeness? Just write your great how-to instructions, and leave it at that.'...most Mac users don’t have to worry about running an antivirus or enabling a firewall on OS X.' I have removed viruses multiple times from people that bought into this sentiment. And it cost them hundreds of dollars for each instance. Keep up the good advice (secure everything you hold dear all the time) and stop it with the bad (you don't even need anti-virus because you bought brand 'x').
- What about Flash Player is that safe? or does it fall in the same category as java
- Why oh why do people continue to promote the fallacy that Mac's are 'rock solid when it comes to security'? Do you read anything other than your own BS?http://www.techweekeurope.co.uk/workspace/macs-immunity-to-malware-exposed-as-fallacy-30566

- I need the JRE and JDK on my mac for my Eclipse IDE to write Java projects.
I updated Java on my Mac OS X system and suddenly there’s an Ask toolbar in Google Chrome? What the heck?? How do I remove this malware?
I think it might be a bit much to call this malware as I don’t think it’s actually doing anything evil or bad to your computer or your browser, but the way that it’s installed as part of the Oracle Java 8.0 update is definitely more than a bit questionable. You do have to okay the install as part of updating your own Java runtime on your Mac system, but I expect that most people are just going to click thru the process without realizing what they’re saying “yes” to, so…
What’s frustrating is that it turns out that not only does the Ask toolbar get installed, but your default search engine is switched from whatever you have set up to Ask.com too. Not good, it’s not a very good search engine and in any case, that’s something you should do consciously, not something that’s done on the sly.
To start, when you go through the install, you will have to click past this window:
So it’s not like they’re entirely hiding the process from us users. Then again, I think this is relatively recent and that previous Java updates were a lot more sly about the process. In any case, if you did install the “Search App by Ask” and the Ask Toolbar, next time you’re on a Web page in your Google Chrome browser, it’ll look like this:
Definitely not to my taste. If I wanted my Web browser to look like a PC’s browser with its half-dozen toolbars, well, I’d be on a PC not a Mac system. ?
To uninstall the toolbar from your Google Chrome system, click on the gears icon on the right side of the Ask toolbar.
Again, that “Uninstall” button is pretty darn front and center.
Click on Uninstall to remove the Ask Toolbar from your Mac’s Chrome browser.
